Cheers, yeah it is a stage 3 chip i bought from Clint Gaskin, I am in another country with a different climate and probably different fuel, so it will never be perfect i guess.

The fuel pressure probably could come down a bit if i sort the leaning out at the top there and that should probably lean it out a bit across the range i presume.

I see your point about the afr aswell the last time i had it on the dyno the afr at the start was 13.8 - 13.0 before the boost came on, hmm.

Thanks.
