Respons TMS Blow Off Valve by Go Fast Bits

On the surface it may look like just another dual-port blow-off valve,but the Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.

Unlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn’t matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.

GFB’s TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves. A factory bypass valve is open until required to shut, however a GFB TMS Valve is shut until required to open.
