The Go Fast Bits DV+ is a great blow off valve solution that is a direct replacement for the weaker OEM unit. This blow off valve features metal construction that ensures for better reliability, and better operation when it comes to holding boost. This blow off valve has been especially designed to fit within the confines of the tight engine bay. This is an innovative two-piece design that features both the valve, and the solenoid which are joined by vacuum hoses. The solenoid can be mounted lower in the engine bay out of the way. This results in more response, and better boost recovery in between shifting. This retains the ECU control, and will not cause compressor surge or turbo flutter.
