Have you adjusted your timing values at idle?Also your main fuel map is just plain odd!There is alot to be gained from smoothing everything off IMO

I would be glad to take a look at your TTmap or a screen shot of the timing if you would like?!I run a GT30 with 3inch maf.

quaife do an atb for the rearof the haldex.Its a bloody shame they dont one for the front of 850's
