    Do you mean Dump Valve(DV) when you say wastegate? If so, you need a re-circulating as opposed to a blow off one used on Jap cars, or the car won't run properly.

    might be your wastegate actuator is stuck if theres no boost at all, just stops the turbos pressure by dumping the usually excess pressure into the exhaust and stops over boosting or so i think.
    could also be your N75 might not be working properly.
    can't really think of owt else
    ou ou ou a hose popped off somewhere??
