1. The response of the turbo is sensitive, the continuous turbo pressure will increase, which will protect the turbo and the throttle, and the leakage sound is also very good! 2.Our valve solution fully integrates with the ECU so that it still the valve is connected to the car, yet when it activates the valve, you now get the traditional dump valve 'whoosh'accompanying your gearchanges. 3.Also our valve is fully serviceable, and rebuildable with a stronger spring should you increase the boost pressure with a remap. 4. Replace the electromagnetic pressure relief valve. The piston diaphragm of the pressure relief valve is easy to rupture, especially when the turbine pressure is higher with the modified power. Our replacement pressure relief valve kit still maintains the normal function of the factory computer-controlled pressure relief valve drive pressure and vacuum, and is complete with electronic signals. 5. The design of this product has been rigorously tested to improve the response of the relief valve and maintain computer control. There will be no fault codes in operation, no problems with the engine self-diagnosis system, and no influence.
