I have been messing with the MAF Compensation table after scaling the MAF and no matter how much fuel is removed it still seems to run rich regardless of IAT under full throttle in the 82-100 range. When AFRs are spot on one drive, on another it would be way richer with no parameters touched.

Replace 02 sensors perhaps-- happened to me recently. AFRs were wild (always rich tho) & acting weird, bad MPG, popping on downhill engine breaking (rich af) some ppl like that but WE know it aint running proper.
otherthan that not much input-- im curious about AIT rescaling myself due to my airbox being wide open.. good luck
