How are the initial #'s found though? Going from stock to bigger injectors to start off where you need to be.
I can't seem to find the post now but I thought I came across you saying 21% would need to be modified for a 42 and 19% for a 39#.
I didn't understand.
I'll send if I can get you the correct fuel injector data..usually when you have Delphi injectors they have a platform that they came installed on. Usually you can download the stock hpt file out the repository and copy paste that correct injector data
