7427 upgrade tuning help understanding

[dave w]

besides the injector flow being changed when you up the psi or put in bigger injectors is there any other perameters or tables that need to be changed

The Injector Offset Tables are parameters that are important for tuning.

The screen shot below shows injector offset tables from 94 Pickup with a 4.3 $OD and a 94 Pickup with a 7.4 $OE. There is "Internet" information the 94 7.4 (28 PSI) uses the same injectors as the 94 4.3 (13 PSI). If the "Internet" is correct, then the fuel pressure difference between the 13 PSI 4.3 injector vs. the 28 PSI 7.4 injector would account for the differences in the injector offset tables?
