How about these IFR?

[KagA152]

Did I do my math right here? Multiplied the stock by 26.11%. Had no knock, changed the injectors and IFR, and now have lots. Lucas 42.5# injectors with a racetronix hot wired pump, stock lines, rails, regulator

What did the IFR Table look like before? Doesn't look far off if you just took stock x 1.2611, Make sure all the injectors work, I've had my share of KR from Injector issues... you can use the "James" method, and flip the rail upside down to watch spray patterns (only do over a cold motor)

stock, or whatever zzp changed them to, was 36.10 to 38.40. im fairly confident the injectors are in good working condition, no problems with a stock table, just really rich obviously

I had hard time tuning those injectors when I used them. Attached are the values I would use. (I left the math in there so you could see how I derived at those values.) Plus, based on your post above, your base IFR was set to the stock IFR for a 2000 GTP. HTH.

EDIT: Made a slight correction to the sheet.
