Re: Is my wastegate shot?

A wastegate on a car under boost will open earlier than it will on the bench do to backpressure pushing the flapper open. The backpressure essentially makes it act like a weaker spring.

When you put aftermarket exhaust on a DSM it makes the car run more boost, sometimes to the point of uncontrollable boost creep.
