A GFB DV+ ensures that all your hard-earned boost makes it to the engine and onto the tarmac. Unsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. A boost leak from the factory diverter valve will cause the ECU to drive the turbo harder to compensate for the loss, resulting in higher turbo RPM, more exhaust backpressure, and hotter compressor outlet temperatures. So even though your tune might still hit target boost, a diverter leak means the turbo is more stressed, and the engine makes less power. The DV+ replaces the factory diverter’s loose-fitting plastic valve with precision CNC machined metal components and a durable elastomer piston seal. Because the DV+ design uses boost pressure to force the piston shut, it doesn’t matter how much boost you throw at it – a DV+ won’t fail, leak, or blow open.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSharper throttle response, faster boost recovery after throttle lift\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFactory electronic diverter valves are binary in operation – they’re either open or shut. Your throttle, however, isn’t. When you make small throttle adjustments, the binary operation of the factory diverter results in abrupt changes in power delivery, which is the very definition of poor throttle response. The DV+ patented “pilot actuation” system allows the piston to open and close progressively, thereby smoothing the power delivery during throttle modulation, and ultimately improving\u003cbr\u003ethrottle response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUnrivalled longevity, Backed by our Lifetime Warranty\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe combination of precision manufacturing, attention to detail, and robust materials mean the DV+ will last a lifetime.

Using GFB’s TMS technology the T9354 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears\u003c\/p\u003e  \u003cp\u003eThe factory BPV (bypass valve) has a couple of key shortcomings, in construction and operation.\u003c\/p\u003e  \u003cp\u003eFirst of all, tuned engines running high boost also produce a lot of heat in the charge air. Because the BPV is situated right on the compressor, it is subjected to the hottest part of the intake charge, and the heat from the compressor cover itself. This can cause the factory diaphragm to rupture, and if that happens and goes undetected for a while, it can cause damage to the turbo, as the ECU will try to compensate for the lost boost pressure by increasing turbo speed.\u003c\/p\u003e  \u003cp\u003eSecond, the operation of the factory BPV is not aimed at throttle response. Because of the soft spring and the solenoid valve that is in-line with the vacuum hose, it can only operate in two states – fully open, or fully shut.\u003c\/p\u003e  \u003cp\u003eThe factory BPV does not have the ability to open and close progressively in response to the existing boost pressure, and throttle response suffers when the valve vents more than it should in situations where you are not fully lifting the throttle. The T9354 solves these issues using proven metal and silicone construction of the valve components, meaning the DV+ will last a lifetime regardless of the harsh conditions.\u003c\/p\u003e  \u003cp\u003eAs for performance, because the DV+ features a carefully selected spring rate AND spring pre-load adjustment, it can operate progressively to help sharpen throttle response. This is the basis of GFB’s TMS principle, which has been shown to reduce the time to peak boost on gearshift by 30%. This benefit is also particularly noticeable in situations where you are modulating the throttle to balance the car in a corner.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eALFA ROMEO 4C 1.75TBi (2013-2021)\u003c\/li\u003e \t\u003cli\u003eALFA ROMEO Giulietta 1.75TBi QV 2010-2016\u003c\/li\u003e \t\u003cli\u003eCHEVROLET Cobalt SS (Turbocharged only) 2008-2010\u003c\/li\u003e \t\u003cli\u003eFORD AUSTRALIA Falcon FG Ecoboost 2.0L 2012-2014\u003c\/li\u003e \t\u003cli\u003eFORD AUSTRALIA Falcon FGX Ecoboost 2.0L 2014-on\u003c\/li\u003e \t\u003cli\u003eFORD AUSTRALIA Focus ST 2.0L EcoBoost (Mk3 2012-18)\u003c\/li\u003e \t\u003cli\u003eFORD AUSTRALIA Focus XR5\/RS 2.5L turbo 2006-2012\u003c\/li\u003e \t\u003cli\u003eFORD AUSTRALIA Mondeo 2.0 Ecoboost 2010-on\u003c\/li\u003e \t\u003cli\u003eFORD Focus ST 2.0L Ecoboost 2012-on\u003c\/li\u003e \t\u003cli\u003eFORD Focus ST\/RS 2.5L turbo 2006-2012\u003c\/li\u003e \t\u003cli\u003eFORD S-Max 2.5T (2006-2011)\u003c\/li\u003e \t\u003cli\u003eLAND ROVER Evoque 2.0T 2011-2015 (petrol only)\u003c\/li\u003e \t\u003cli\u003eLAND ROVER Freelander II 2.0T 2013-2015\u003c\/li\u003e \t\u003cli\u003eOPEL Corsa OPC\/VXR 1.6T 2007-2014\u003c\/li\u003e \t\u003cli\u003ePORSCHE 911 all 997 twin turbo models 2006-2012\u003c\/li\u003e \t\u003cli\u003eVOLVO C30 T5 2.5L Turbo 2006-2012\u003c\/li\u003e \t\u003cli\u003eVOLVO C70 T5 2.5L Turbo 2006-2012\u003c\/li\u003e \t\u003cli\u003eVOLVO S40 T5 2.5L Turbo 2004-2012\u003c\/li\u003e \t\u003cli\u003eVOLVO S60 \u0026amp; V60 T5 2.0T 2010-2013\u003c\/li\u003e \t\u003cli\u003eVOLVO V40 T5 2.5L 2012-14\u003c\/li\u003e \t\u003cli\u003eVOLVO V50 T5 2.5L Turbo 2004-2010\u003c\/li\u003e \t\u003cli\u003eVOLVO XC60 T5 2.0T 2012-2017\u003c\/li\u003e \u003c\/ul\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-DV+-Diverter-Valve-Ford-Volvo-Porsche-Alfa-Romeo-Borg-Warner-Turbo-T9354\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":67893351416128,"sku":"T9354","price":213.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/T9354.jpg?v=1793179693"},{"product_id":"gfb-dvx-sound-adjustable-diverter-valve-t9654","title":"GFB DVX Sound Adjustable Diverter Valve T9654","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-DVX-Sound-Adjustable-Diverter-Valve-Ford-Volvo-Porsche-Borg-Warner-Turbo-T9654\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003eGFB’s DVX takes the extremely popular DV+ Diverter Valve and adds dual venting outlets along with our patented Venting Bias Adjustment System.

GFB is no stranger to dual port BOVs. In fact, GFB pioneered the design in 1999, following up with the patented venting bias adjustment system in 2001.

Certainly, if the BOV is not designed or adjusted correctly, at least some of these may be true.\u003c\/p\u003e  \u003cp\u003eWhen you vent a BOV to atmosphere, you're letting air out of the system that has been measured by the airflow meter, so the ECU will continue to inject fuel for that missing air, hence the issues with over-fuelling that can occur. However, by controlling HOW MUCH the valve vents, WHEN it vents, and for HOW LONG, the Respons can be configured to vent a portion of air to atmosphere at a time and of a volume that least affects the fuelling to the point where there are no negative side-effects. Since our competitors do not have a means for adjusting the amount of air that is vented to atmosphere, they are unable to achieve the same success that a Respons does on even the most sensitive engines.\u003c\/p\u003e  \u003cp\u003eIf everything you've heard tells you a BOV won't work on your car, try a GFB Respons - you will be surprised!\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eGFB Respons TMS Features:\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eBoost holding\u003c\/p\u003e  \u003cp\u003eUnlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn't matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.\u003c\/p\u003e  \u003cp\u003eThrottle response and boost recovery\u003c\/p\u003e  \u003cp\u003eGFB's TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves, which can be summarised as:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eA factory bypass valve is open until required to shut.\u003c\/li\u003e \t\u003cli\u003eA GFB TMS valve is shut until required to open.\u003c\/li\u003e \u003c\/ol\u003e  \u003cp\u003eThis difference in operating methods means that the GFB valve only vents when required, and only enough air to prevent compressor surge.

In 2004, GFB released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types. For the owners of all other types of GFB valves, we have now released the 5702, a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesn't cut it.\u003c\/p\u003e  \u003cp\u003eThe 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch. Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet. Respons valves will typically not generate the velocity required to whistle when set to 50\/50 venting.\u003c\/p\u003e  \u003cp\u003eThis part is recommended for Respons and Deceptor Pro II valves EXCLUDING T9003 \u0026amp; T9503.\u003c\/p\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Whistling-Trumpet-for-GFB-Response-Deceptor-Pro-BOV-Suits-Low-Boost-5702\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":67893702033728,"sku":"5702","price":44.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/5702_9e7407f9-5797-4c80-9d92-440bb34e3814.jpg?v=1793180473"},{"product_id":"gfb-respons-deceptor-pro-bov-blanking-plug-6107","title":"GFB Respons\/Deceptor Pro BOV Blanking Plug 6107","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Respons-Deceptor-Pro-BOV-Blanking-Plug-6107\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Respons-Deceptor-Pro-BOV-Blanking-Plug-6107\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":67893705048384,"sku":"6107","price":15.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/6107_2b442fc8-414a-497f-b3de-807bfa8758f7.jpg?v=1793180491"},{"product_id":"gfb-deceptor-pro-ii-electronic-bov-blow-off-valve-25mm-t9525","title":"GFB Deceptor Pro II Electronic BOV Blow Off Valve 25mm T9525","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Deceptor-Pro-II-Electronic-BOV-Blow-Off-Valve-25mm-Audi-VW-Ford-XR6T-Bosch-Replacement-T9525\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003eNow you can control the sound of the BOV from inside the cabin!\u003c\/p\u003e  \u003cp\u003eSo how much more can you do with a blow-off valve?

Using GFB’s TMS technology the T9360 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears\u003c\/p\u003e  \u003cp\u003eThe factory BPV (bypass valve) has a couple of key shortcomings, in construction and operation.\u003c\/p\u003e  \u003cp\u003eFirst of all, tuned engines running high boost also produce a lot of heat in the charge air. Because the BPV is situated right on the compressor, it is subjected to the hottest part of the intake charge, and the heat from the compressor cover itself. This can cause the factory diaphragm to rupture, and if that happens and goes undetected for a while, it can cause damage to the turbo, as the ECU will try to compensate for the lost boost pressure by increasing turbo speed.\u003c\/p\u003e  \u003cp\u003eSecond, the operation of the factory BPV is not aimed at throttle response. Because of the soft spring and the solenoid valve that is in-line with the vacuum hose, it can only operate in two states – fully open, or fully shut.\u003c\/p\u003e  \u003cp\u003eThe factory BPV does not have the ability to open and close progressively in response to the existing boost pressure, and throttle response suffers when the valve vents more than it should in situations where you are not fully lifting the throttle. The T9360 solves these issues using proven metal and  silicone construction of the valve components, meaning the DV+ will last  a lifetime regardless of the harsh conditions.\u003c\/p\u003e  \u003cp\u003eAs for performance, because the DV+ features a carefully selected spring rate  AND spring pre-load adjustment, it can operate progressively to help sharpen  throttle response. This is the basis of GFB’s TMS principle, which has been  shown to reduce the time to peak boost on gearshift by 30%. This benefit is  also particularly noticeable in situations where you are modulating the throttle  to balance the car in a corner.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e2016-2017 Ford Focus RS Mk3 LZ\u003c\/li\u003e \u003c\/ul\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-DV+-Diverter-Valve-Ford-Focus-RS-Mk3-LZ-16-17-T9360\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":67894356279616,"sku":"T9360","price":213.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/T9360.jpg?v=1793182527"},{"product_id":"gfb-vta-atmosphere-diverter-valve-t9460","title":"GFB VTA Atmosphere Diverter Valve T9460","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-VTA-Atmosphere-Diverter-Valve-Ford-Focus-RS-Mk3-LZ-T9460\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003e\u003cstrong\u003eThe VTA is a performance blow-off valve solution for vehicles with an electronic factory diverter valve.\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eIf you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that!

The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance. The factory diverter valve can only operate in two states – open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition.\u003c\/p\u003e  \u003cp\u003eGFB pioneered the use of “pilot operation” in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve.\u003c\/p\u003e  \u003cp\u003eIt is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.\u003c\/p\u003e  \u003cp\u003eKey features:\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eTMS Technology for faster boost recovery on gearshift and during throttle modulation\u003c\/li\u003e \t\u003cli\u003eImproved boost holding ability\u003c\/li\u003e \t\u003cli\u003eAtmosphere venting for blow-off sound\u003c\/li\u003e \t\u003cli\u003eRetains ECU control\u003c\/li\u003e \t\u003cli\u003eSimple, direct bolt-on kits include everything you need to install\u003c\/li\u003e \t\u003cli\u003eManufactured in Australia in accordance with ISO 9001\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003eVTA or DV+?\u003c\/p\u003e  \u003cp\u003eDepends if you want sound or not.

GFB is no stranger to dual port BOVs. In fact, GFB pioneered the design in 1999, following up with the patented venting bias adjustment system in 2001. This technology is not just a gimmick; it's the key to getting a blow-off sound without the issues (unlike other valves), and is exclusive to GFB.\u003c\/p\u003e  \u003cp\u003e\u003cem\u003e\"I thought venting to atmosphere couldn't be done on a car with an airflow meter, so how does the Respons do it?\"\u003c\/em\u003e\u003c\/p\u003e  \u003cp\u003eWe've all heard the stories and seen people get shot down on forums when they ask about BOVs. Common responses are \"your car will stall, backfire, run rich, go slower, or rip a hole in the space-time continuum that will bring about the end of the universe\". Certainly, if the BOV is not designed or adjusted correctly, at least some of these may be true.\u003c\/p\u003e  \u003cp\u003eWhen you vent a BOV to atmosphere, you're letting air out of the system that has been measured by the airflow meter, so the ECU will continue to inject fuel for that missing air, hence the issues with over-fuelling that can occur. However, by controlling HOW MUCH the valve vents, WHEN it vents, and for HOW LONG, the Respons can be configured to vent a portion of air to atmosphere at a time and of a volume that least affects the fuelling to the point where there are no negative side-effects. Since our competitors do not have a means for adjusting the amount of air that is vented to atmosphere, they are unable to achieve the same success that a Respons does on even the most sensitive engines.\u003c\/p\u003e  \u003cp\u003eIf everything you've heard tells you a BOV won't work on your car, try a GFB Respons - you will be surprised!\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eGFB Respons TMS Features:\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eBoost holding\u003c\/p\u003e  \u003cp\u003eUnlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn't matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.\u003c\/p\u003e  \u003cp\u003eThrottle response and boost recovery\u003c\/p\u003e  \u003cp\u003eGFB's TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves, which can be summarised as:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eA factory bypass valve is open until required to shut.\u003c\/li\u003e \t\u003cli\u003eA GFB TMS valve is shut until required to open.\u003c\/li\u003e \u003c\/ol\u003e  \u003cp\u003eThis difference in operating methods means that the GFB valve only vents when required, and only enough air to prevent compressor surge. For example, during a gearshift it is possible to preserve a small amount of boost pressure for a short duration.

GFB is no stranger to dual port BOVs. In fact, GFB pioneered the design in 1999, following up with the patented venting bias adjustment system in 2001. This technology is not just a gimmick; it's the key to getting a blow-off sound without the issues (unlike other valves), and is exclusive to GFB.\u003c\/p\u003e  \u003cp\u003e\u003cem\u003e\"I thought venting to atmosphere couldn't be done on a car with an airflow meter, so how does the Respons do it?\"\u003c\/em\u003e\u003c\/p\u003e  \u003cp\u003eWe've all heard the stories and seen people get shot down on forums when they ask about BOVs. Common responses are \"your car will stall, backfire, run rich, go slower, or rip a hole in the space-time continuum that will bring about the end of the universe\". Certainly, if the BOV is not designed or adjusted correctly, at least some of these may be true.\u003c\/p\u003e  \u003cp\u003eWhen you vent a BOV to atmosphere, you're letting air out of the system that has been measured by the airflow meter, so the ECU will continue to inject fuel for that missing air, hence the issues with over-fuelling that can occur. However, by controlling HOW MUCH the valve vents, WHEN it vents, and for HOW LONG, the Respons can be configured to vent a portion of air to atmosphere at a time and of a volume that least affects the fuelling to the point where there are no negative side-effects. Since our competitors do not have a means for adjusting the amount of air that is vented to atmosphere, they are unable to achieve the same success that a Respons does on even the most sensitive engines.\u003c\/p\u003e  \u003cp\u003eIf everything you've heard tells you a BOV won't work on your car, try a GFB Respons - you will be surprised!\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eGFB Respons TMS Features:\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eBoost holding\u003c\/p\u003e  \u003cp\u003eUnlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn't matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.\u003c\/p\u003e  \u003cp\u003eThrottle response and boost recovery\u003c\/p\u003e  \u003cp\u003eGFB's TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves, which can be summarised as:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eA factory bypass valve is open until required to shut.\u003c\/li\u003e \t\u003cli\u003eA GFB TMS valve is shut until required to open.\u003c\/li\u003e \u003c\/ol\u003e  \u003cp\u003eThis difference in operating methods means that the GFB valve only vents when required, and only enough air to prevent compressor surge. For example, during a gearshift it is possible to preserve a small amount of boost pressure for a short duration. Then, when the throttle is then re-opened, peak boost is reached faster than if all pressure is lost (as is the case with the factory valve that remains fully open too long).\u003c\/p\u003e  \u003cp\u003eGFB's patented venting bias adjustment:\u003c\/p\u003e  \u003cp\u003eTwisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.

Try a GFB Respons; you'll be surprised! On the surface, it may look like just another dual-port blow-off valve, but the Respons is actually much more than that. Featuring GFB's patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets. Why is this so important? Two key reasons:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eAdjust how loud the blow-off sound is.

GFB is no stranger to dual port BOVs. In fact, GFB pioneered the design in 1999, following up with the patented venting bias adjustment system in 2001. This technology is not just a gimmick; it's the key to getting a blow-off sound without the issues (unlike other valves), and is exclusive to GFB.\u003c\/p\u003e  \u003cp\u003e\u003cem\u003e\"I thought venting to atmosphere couldn't be done on a car with an airflow meter, so how does the Respons do it?\"\u003c\/em\u003e\u003c\/p\u003e  \u003cp\u003eWe've all heard the stories and seen people get shot down on forums when they ask about BOVs. Common responses are \"your car will stall, backfire, run rich, go slower, or rip a hole in the space-time continuum that will bring about the end of the universe\". Certainly, if the BOV is not designed or adjusted correctly, at least some of these may be true.\u003c\/p\u003e  \u003cp\u003eWhen you vent a BOV to atmosphere, you're letting air out of the system that has been measured by the airflow meter, so the ECU will continue to inject fuel for that missing air, hence the issues with over-fuelling that can occur. However, by controlling HOW MUCH the valve vents, WHEN it vents, and for HOW LONG, the Respons can be configured to vent a portion of air to atmosphere at a time and of a volume that least affects the fuelling to the point where there are no negative side-effects. Since our competitors do not have a means for adjusting the amount of air that is vented to atmosphere, they are unable to achieve the same success that a Respons does on even the most sensitive engines.\u003c\/p\u003e  \u003cp\u003eIf everything you've heard tells you a BOV won't work on your car, try a GFB Respons - you will be surprised!\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eGFB Respons TMS Features:\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eBoost holding\u003c\/p\u003e  \u003cp\u003eUnlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn't matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.\u003c\/p\u003e  \u003cp\u003eThrottle response and boost recovery\u003c\/p\u003e  \u003cp\u003eGFB's TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves, which can be summarised as:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eA factory bypass valve is open until required to shut.\u003c\/li\u003e \t\u003cli\u003eA GFB TMS valve is shut until required to open.\u003c\/li\u003e \u003c\/ol\u003e  \u003cp\u003eThis difference in operating methods means that the GFB valve only vents when required, and only enough air to prevent compressor surge. For example, during a gearshift it is possible to preserve a small amount of boost pressure for a short duration. Then, when the throttle is then re-opened, peak boost is reached faster than if all pressure is lost (as is the case with the factory valve that remains fully open too long).\u003c\/p\u003e  \u003cp\u003eGFB's patented venting bias adjustment:\u003c\/p\u003e  \u003cp\u003eTwisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.
