GFB Respons TMS valve for Nissan GTR features both the GFB patented adjustable bias venting system, and the GFB TMS advantage. (2 Valves Included)
The TMS range from GFB is designed specifically for the purpose of turbo lag reduction and improving throttle response. Tests show TMS features can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears. If you want noise with your performance, the GFB TMS BOVs can deliver it! 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.
