Just finishing up my return conversion on my truck. I cant get ahold of my tuner, so im trying to do the intial tuning changes myself. Let me know if im on the right track. As far my IFR vs KPA VAC table, I just copy the 0 KPA and paste across the entire table? And for the Offset vs voltage vs kpa, again copy the 0 KPA table and paste this to the entire table aswell?

I included pictures of my current table for 83lb @ 4 bar injectors

Yes that's all correct.

These changes should get me running, and then the VE table is what will need to be adjusted after that to get me dialed in? I assume WOT will be very rich at this point?

It will only be rich if you have adjusted it previously to try to account for injectors that were too small or a fuel pump that was dropping pressure. Ideally, VE won't change if the characterization information for your injectors is accurate.

Yeah the fuel pressure was dropping into the mid 40's which was the reason that I decided to convert to a return style

Those changes are correct. Your ve table will most likely be rich as hell on top now.

Maybe I can get away with a smaller pulley to counter act the richness lol

It's most likely going to be really rich, and don't forget about timing. Just adding boost to offset fuel isn't the answer.
