The GFB Respons blow off valve is designed specifically with the aim of improving throttle response and reducing turbo lag.
On top of the TMS benefits, the Respons also packs GFB’s patented adjustable venting bias system found on the Stealth FX. So if you want noise with your performance, the Respons can deliver! By fine-tuning the venting ratio, you CAN achieve a blow-off sound WITHOUT throwing a CEL, running rich, stalling, using more fuel or causing any other problems commonly associated with atmoventing valves on cars with MAF sensors.
Tests show that TMS features can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.
Available in a range of universal hose-mount or direct bolt-on configurations for many popular models:
