Big Injector (2150cc) & 6l90 Tuning

[1INSANEGTO]

Ok we know if your MAF is incorrectly scaled the TCM receives an erroneous torque value and makes incorrect shift adjustments. Why it is so critical to have a spot on engine tune with the 6L80/90.

With the above stated getting the 2150cc injectors scaled correctly the MAF has been divided x2 (50%) so they are low thus causing issues with the trans now. Few people I talked said to mess with the PE table but that's wot what about cruising. Even with messing with the PE tables I don't think we will get the MAF back in line but maybe 20%.

Not sure on options but few ideas floating around in the air now.

1. Relocate the MAF sensor to the intercooler tank.
2. Go to a lower cc injector (ID1300) and mess a little with the PE table to get things in line.

Thoughts? 1076rwhp on e85 (low boost) thus far but I want moar but I want a shifting trans too lol.

Did you scale the pressure shift areas in the tune as well. EX: Take value in the shift pressure areas by gear at 500ft/lbs and move to 250ft/lbs as your tune is scaled by 1/2, you need to move the shift pressures around as well.
