How are you engaging the S/C clutch? Wired to be on constant or controlled by the ecu. n standard form the black and red wire is 12V and the black and yellow wire is ground through the S/C relay which is controlled by the ecu.
The air bypass valve governs maximum boost so if this is stuck open you will lose boost. Did you fit a boost gauge?
