So I installed a new fuel rail with some 50# injectors. I got them from FIC and they said
"Tuning is a snap as it is the same injector that is programmed in the LS1 computer Set the new IFR and go!" And that's what I did now the A/F is all over the place and WOT pulls it takes a second for power to kick in. I have been using the tuning school books to help me but it's not helping to much. Please let me know what tables I need to play with or if you see something obvious. Thanks
