Is there a way to compensate for this?
Previous owner of my car put 17lb injectors and a cam. Obv they never tryed to adjust the computer for the cam and bigger injectors so my car is running really rich. I contacted a dyno/speed shop and they said they have no programs to tune my vehicle. It's a 2.8 v6 mpfi. Is there anyways I can get my ecu to compensate for the cam and injectors on my 7302'? Or do I have to take these out and return to stock?
Any suggestions would be awesome

what mask is it?
if it's like a normal speed-density mask, you'll just have to change the BPW vs EGR table.

great... MAF. i have a 3A XDF, but i'm not seeing either a scalar or table for the usual items.
you may have to change the "Injector Pulse Width Vs. Load Value" table by the amount of difference there was with the old injectors compared to the new ones. or maybe the LV8 scale factor...
i'm still lost when it comes to MAF, so someone else could definitely give a better answer....

it seems having a 2.8 is just a headache all around. Can't till next year when I hopefully swap my engine.
