Alright starting with a 99 which of course has 26lb injectors.
Swapped in some stock 28lb injectors.
Well the 98 and 02 flow rate vs KPA tables are the same so I swapped them in to my 99's tune.
What about the offset vs volts vs VAC, the FA multi stage 1 vs time, the boundary and short pulse adder.
Should I copy these tables to my 99 and if so which do I pull them from, the 99 and 02 don't match on these tables

I would upgrade your 99 OS to a 2002 and do a Full re-flash if it was me. That way you eliminate the backup VE table and gain a few other tables. Also, you won't have to worry about the fueling tables as they are already setup for the 28lb injectors.

that would lose all my other tuning, not to mention i would have to buy more credits

You can't do a full reflash to a 2002 os with HPT?

If that is the case then I would do a compare to the 2002 file and copy over the values.

I agree, just do a compare to the later vehicle (02) and 0 it out to make your tune identical to the 02 as far as the injectors go.
