Car has a ls2 with the e40. Cold air intake and long tube headers. After getting the maf tuned in via wide band the calc air per cylinder is down to like .65-68 grams per cylinder at wot. Which is now making the timing table messed up. Also when I'm logging the ap cyl e40 pid it will not transfer over to the tune tool when high lighting the log in areas. Rpm is there but grams/cylinder just sits at 1.00 regardless of what they scan shows it is. I don't think the issue is the maf sensor but possibly the intake. It was really rich on the bottom end and top end. Prior to any tuning he had the p0172 and p0175 codes
