The clutches haven't been an issue and the research/reading I did before the PS2 upgrade said that there shouldn't be a problem as my goal is around 450 whp using pump gas + octane booster as a daily driver. If you want boost above 16 psi above 6k rpm you should look into getting the lighter M2/M3/M4 flywheel. There's much discussion about the misfire and I could verify that I got the misfire after the PS2 and before the M flywheel swap and no longer get the misfire. The misfire is harsh enough somethings to kick the DME into limp-mode, so something you may want to address.

What brand/.model muffler are you running? Is it a Flo-Pro?
