Here are some dyno sheets comparing the AutoT chip for the MAF vs a custom Steve W chip. engine is a stock 3.2L, cat by pass and stock muffler.
The autot chip for the MAF had a rich A/F mixture. Steve got the mixture where it should be and flattened it out throughout the rpm range. My goal was to get the a/f ration corrected but also got some extra hp and tq. The car runs great at all rpms, idle, WOT all perfect. I give two thumbs up for Steve's custom chips vs the autot.
