I built my own transmission friendly PE vs RPM (vs time i guess) table... It removes the time part and focuses on dumping extra fuel at the shift points.

Do you personally ever touch PE vs TPS?
I do some fancy crap on the turbo drag cars, typically not much if any on SC cars.

Am I right when I say it must be one of both of those?
PE vs coolant temp is the "main" commanded PE afr table.

How do I get the correct IFR's then for 42lb injectors (if they are wrong)?
I use the narrowband to help... Eyeball the trims to see what direction they generally go and go from there. (between -10 and -6 most the time? subtract 7% and consider it tuned) I have my own math saved off thats usually close enough for me not to ever adjust them after the fact unless someone is paying me alot of money or they are convinced i need spend 3 days working on it and I want to look busy tuning their car.

Remember fuel trims take a few power cycles to learn correctly, so go with a base flash and drive around for awhile... throw the gauge up on the scan tool and glance at it while you are driving around to get an idea of how much adjustment you might want to make... tune WOT/PE a while after you make the IFR correction.
