Go Fast Bits Respons TMS Direct-fit Blow-Off Valves with TMS Advantage T9000

Go Fast Bits Respons TMS direct-fit blow-off valves with TMS Advantage allows you to infinitely vary how much air is recirculated or vented to atmosphere. Simply by twisting the adjustment ring, you can change the sound of your BOV from silent to ear-shattering! GFB's patented venting bias adjustment system can be tweaked between full recirculation (silent) and full atmosphere (loud). With the Turbo Management System (TMS) technology, Respons BOVs can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears, offers better throttle response, and unlimited boost-holding. If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons valves can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues.
