Boost logs look ok, actual and requested fairly out in places but the actual looks ok. Maf readings seem about right.
As for the AFR... like i said before this is a built in emissions related function BUT with 1.5 bar OB it's not ideal, i run these as rich as 12.5:1 on WOT which helps to cool and make the torque too.
Without seeing the car it's hard to comment, i mean it could be knocking it's head off.
Take a log from 118 (i think) should be duty and charge temp.
Also try to log the advance CF, cant remember which channel it's on.
Also what fan(s) were on the car when it was run?
