Go Fast Bits TMS Respons Hybrid Blow Off Valve Subaru WRX 2002-2007 / STI 2004-2014 / Forester XT 2006-2008

As the name suggests, the GFB Respons is designed specifically with the aim of improving throttle response and reducing turbo lag.

What’s TMS? GFB’s Turbo Management System is the term they apply to their diverter valves that have features designed specifically for the purpose of turbo lag reduction.

Tests show that TMS features can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

On top of the TMS benefits, the Respons also packs GFB’s patented adjustable venting bias system found on the Stealth FX.

This unique system allows the amount of air vented to either recirc or atmosphere to be infinitely varied to change the venting sound like a stereo volume dial.

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 atmo-venting valves on cars with MAF sensors.
