Boost leak test? What plugs are in the motor and what gap?If your profile is up to date, and you still have the greddy kit w/external gates...are your wastegates opening up at all? Greddy boost controllers can be a pain to fine tune (I'm assuming you have the profec B-spec 2), especially if you don't have the vacuum lines for the solenoid routed properly. Have you checked the boost solenoid for proper function? There's a lot of things or just A simple thing that could be keeping your Z from running lie it's supposed to.
