So I just re-mounted my wg so that it will clear and allow the flapper to open fully=no more creep. It hits full boost (10psi) around 3-3.5K and feels real good getting there, BUT....it won't hold full boost for long. I don't know what it is, but once I hit full boost and continue to floor it, my revs jump up a bit as if I just disengaged the clutch, then they drop way back down. Meanwhile, I'm losing boost. What could be causing this? Is my clutch slipping/dying or is it another wg issue or what?
