Nice read on your thread dude... you're going down similar avenues to me and i'm having the exact same questions about clutches. I've got a Revo Stage 1 map on mine and it's slipping but intermittently. I think i've found the issue (PCV leak) but still i wonder whether the standard clutch is up to the job of a Stage 2... doubtful at 115k on the clock!
Anyway... look forward to reading more on this! It's a great colour by the way.
