You running 93 octane or Race fuel??When the kit was first installed, it pulled 118rwhp and 75tq at 11psi. The mcx mapping is a bit rich but that's where I'd rather be. We might play with fuel at 11psi next time on the dyno, definetly will play with boost and see how mapping does.
So far, clutching has been flawless and belt life is above expectations, with STM clutches. I'm at approx 900km on my max, half of those boosted and still on original belt and last time I checked, belt still looked fine so I left it on.
