That's a bit of a disappointment, where in the rev range did it make that? You'll have to post up the graphs..

MAF is a possibility, even if it is slightly dirty it can cause a dodgy reading. I wonder if having it directly above the filter box is the best placement? My CDA attached directly to the AD intake pipe, the MAF then comes after that, just before the flexi-section. I reckon this should mean the airflow is pretty constant just after coming out of the AD pipe, so should give a very true reading.. Anyway, A/F reading should breathe some more light on things. Problem with the V6 engines is how rich they have to run at high revs to avoid detonating.. I've heard of 11:1 when running at WOT in open loop..

261bhp is much better.. How does Bacon's feel to drive in comparison? I think Angel were claiming 267bhp for remap alone from standard..
