Turbochargers are a vital part of your diesel truck and in order to keep them running their best, you need to keep it protected. If you're running a stock charger you may not have experienced the “surge”, however if you are running an aftermarket turbo, especially a larger one, you know exactly what we are talking about. When you let off the throttle quickly while the engine is under a load, the air the engine was consuming stops. This can be catastrophic to your turbo wearing out thrust bearings, and even possibly exploding the compressor wheel. BD Diesel has designed a new TurboGuard Kit featuring adjustable valve opening pressure and a microprocessor with six different custom settings including valve opening pressure, activation sensitivity, clutch cancellation and more. This TurboGuard comes with steel adapter and is available with red or silver valve.  Fits most applications. Older non-APPS or TPS vehicles such as 1994-1998 5-Speed 12-Valve Dodges require specific application.
