NOt sure how releavant this will be to you since i was on a 2 bar SD tune, BUT....
The cause of all my problems was the fueling, the transition to PE was a rock, was jumping from 14.0 commanded to something off the scales it was so fat, IIRC, i actually fouled my plugs doing that as well.
When i we pulled up the graph it was like a cliff, and was instant, it was not linear like it shouldve been. Furthermore, we had our transition to PE all out of whack,
Im not sure how a MAF tune works, but basically, we had the PE enabling way to Soon, Map vs. TPS vs. RPM or something like that,
Unfortunatley, the only real advice i can give you in this situation, if you dont have HP tuners, you probably need to get it, either A. so you can log for the people who sent the tune, or B. tune yourself.
Or, bring it down sat and let Joe mess with it, as he is one of the best MAF tuners ive seen.
If it was me, id ditch the damn MAF and drop a 2bar Custom os with RTT in her on Hp tuners and run and gun. On the fly tuning and when you get her how you like her, write the changes and save.
But, like i said, the first thing that comes to my mind, given my experience, is the fuel table and PE, again, im not sure if PE is utilized in a maf tune.
Im sorry this is all i could give you.
