As the title states-I have delphi 38lb injectors installed on my new setup-The car is a '99 Trans Am. I had the stock 26lb injectors with a custom tune. I need to get my car started and on the trailer to take it to my chassis guy. I am running around like a chicken with it's head cut off trying to make the EFI race in BG (Super Stock).

I received my EFI live yesterday-How do I change the inj. scaling to compensate for the new injectors? I have seen the link to the excel spreadsheet on ls1tech.com ; but it has 58 psi listed? I thought the ls1's had 55 psi fuel pressure. The delphi's (white) are 38's right?-but 42's at my fuel pressure?

Please Help-I just need this one tweek on the tune to get it running. I am planning on Auto tuning it next week sometime.

Thanks in advance-sorry for the long first post.
