Product Details

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 we apply to our 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 atmoventing valves on cars with MAF sensors.

How GFB’s patented venting bias adjustment works
Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.
