ok long story short, clutch was dieing for a few months but before I could afford a clutch I just babied my 327rwkw ba ute about. once I had my new clutch installed and run in I discovered the ute had a bad miss once it was hitting boost. -to try fix this I regapped the plugs which fixed the miss a bit -new iridium plugs, fixed it further but its still there.. the miss seems to pop up around 13-15psi at above 90% throttle. should my next step be new coilpacks? cheers, danny
