Seems my boost is not going into my engine, the boost gauge will be pinned, turbos spooling up lots and the car makes lots of noise, but the boost is not going into the engine. Its not boost leakes for sure. I am just unsure what needs to be fixed or replaced here. Is it the wastegate, or some valve on the cast iron part of my turbo just letting all my boost go right into my exhaust. Anyone had this problem?
