How much boost over stock are you running?
Is the computer having issues adjusting for the increase of incoming air?
Maybe your oxygen sensors have expired and are not sending the computer the necessary info to process the incoming air.

I suspect rings gave out...and or nikasil sleaves got messed up somehow...
