Also, 1300+ seems really high. Have never seen that with any idi that I have been around. Do you have the bigger outlet housing on the turbo, and bigger down pipe? I know you said you advanced the pump a ways from stock, but unless the timing was seriously retarded before, I think you probably are way too advanced.
I have never seen timing advanced beyond the factory spec do anything but make more noise and more smoke.
