You need to increase the load limit at 3800 from 1.0 to 1.1 and return your maf scale to the original smooth one in that area. (See revworks load limits)
Which headers do you have?

The car has a OFT, OFH and a Takeda intake and is running Wayno's v86 tune on United E85.
Log 1: This when I first noticed it. It went up to 14.36 AFR when command was 12.59.

Log 2: I then added 10% to the 3.2v MAF value. It dropped to 13.78 AFR when command was 12.59. Still too lean but heading in the right direction.

Log 3: I added another 8% to the 3.2v MAF value. AFR went back up to 14.24 when command was 12.59. Not what I was expecting.

I didn't want to keep increasing this as it seems something else is off. Any ideas? Could I have a faulty MAF sensor? |
