Injector Compensations:
The purpose of injector compensation is to make up for the time it takes for an injector to open and then close. The proper values can be difficult to obtain, so many times they are guessed at based on results. Which in many cases works out OK.
In general terms the higher the fuel pressure the longer it takes for an injector to open. Increased fuel pressures are more prevalent on TBI systems. And as such should have the injector compensation values increased. Check the 5.4l calibration with the 80# injectors at 22 psi. Compare those values with some stock calibrations. That will give an idea of what values can be used.

Injector correction multiplier. Voltage based. I understand a lower voltage will make inj opening slower. So I upped those 10% for 80 lbs inj @ 19.5 FP. 14.4 I assume is neutral being at zero so I changed to 2.34.
Injector correction offset. Again V based. I added 10%.
Please define correction offset.
