Hey, i just installed my 42.5lb injectors into my 02 GTP. I tried to multiply the FlowRate vs. KPA table as i read on here by .87 or so, and it made the car bog out at high rpms. Then i read to multiply by 1.18 or so and it made it knock like crazy, so i went back to the stock setting from DHP and it seems to be fine, only getting 2.5* of KR at 100mph 100%TPS. I posted the scan, any input is appreciated.

Just went over your scan. i'm not all to sure but only a couple * knock is not bad. i noticed that your car went a little lean your LTFT should be at 0 and that would get rid of that little bit of knock. i can post a scan so you can see how at 0 there's almost 0* knock

You should mutliply your IFR table by about 1.18. Your running dog rich in PE. Your O2's are over 1000 which is really high. You also need add to your log Air Fuel Ratio Commanded Lo Res and Mass Air Flow Hz. I would also add Trans Current Gear and drop Injector Pulse Width Bank 2 since you don't have a second bank. You need to change your IFR table then work on your MAF table. Your LTFT's are terrible. You don't need to go WOT to work on your MAF table. Just get log data up to about 7500hz. Once you get your LTFT's in a good range, about -5 to +5, then you can work on your WOT fueling.
