GFB Respons TMS Adjustable Bias Atmospheric / Diverter Valve

The Respons II Bias-Adjustable Blow-Off Valve from Go-Fast Bits is designed to solve a number of problems with your factory diverter valve and other aftermarket blow-off valves.Unlike many twin-port dump valves the Respons II is fully adjustable. It offers a complete range of adjustability from fully atmospheric to fully recirculating. As the atmospheric route opens, the recirculating route closes.This means you can finetune the exact amount of noise you want out of the valve and carefully ensure that you have no driveability issues.TMS is technology developed by Go-Fast Bits designed to improve driveability and throttle response.Your factory diverter valve will be designed to open partially under most conditions except full boost.Go-Fast Bits take the opposite approach and design their valves to stay closed except when they need to open.This means that whereas your factory valve will let the turbo spool down and pressure in the intake system drop completely, theirs keeps a little pressure in the system. This makes a huge difference to turbo spool times. By not requiring you to build boost again from scratch you should be able to get back on boost quicker.Staying closed under full and part load should improve driveability too. Under part load it ensures you're getting full boost.Under full load and you're ensuring that you're getting all of the power out of the engine. The valve is built to stay closed under even very high loads.
