The GFB Respons TMS takes the entry level Mach 2’s capability a few steps further. As a dual-port blow off valve, it maintains the throttle response optimization and boost holding capability of the Mach 2 and adds Go Fast Bits’ patented venting bias adjustment system. This gives you the capability to precisely tune the GFB Respons for the amount of air vented from either outlet. You can recirculate 100% of the air, or vent fully to the atmosphere and anywhere in between. As such, the GFB Respons allows you to control the noise level off the blow off valve, without causing back-fire or stalling or any other BOV related issues. As with most other Go Fast Bits kits, the GFB Respons is a bolt on affair, with no other modifications required other than the removal of the factory installed valve, and replacement with the Respons TMS.
