I doubt your boost gauge is faulty. It would read low or not at all if it was hooked up wrong.


My guess is that something is wrong with your wastegate. If it's not opening under boost to regulate boost levels.. your turbo will run much higher PSI levels.

couple things to check..

-Is your wastegate actuator connected to the flapper arm?
-Is a vac line connected to the WG solunoid?
-With the WG actuator arm disconnected do ethe the flapper arm move freely?
