got the new combo running the other day on my old tune(slightly tweeked) and my old injectors to get the motor broken in. we switched them today, imputed all the injector data but the car is running pig rich at idle and thru the rpm range. doesent matter how much fuel we pull out it still stays the same afr (low 10s). I even played with fuel pressure, went from 30 all the way up to 65 and it makes no difference! its like theres another table or something commanding it to run really rich. any ideas?

Left my laptop at the dyno. We took so much fuel out that it shouldn't have even run but it was still running rich

Just noticed on the website I bought the injectors from that the data is for efi live. Would that make a difference what software I'm using?

What operating system and pcm? Some gen 3 pcms will need a cax file added to be able to decrease b9021 as they don't list it in the 411 pcm for some reason. Look up cax file and b9021 on the efilive form if you need the download and instructions

What was the injector pw at idle?

Is the fuel milligrams table stock? If so it needs to be reduced for that size injector.
