Default EFI Live HELP
I currently have an 02 T/A that is highly modified. It has a F1C Procharger on a built 451 LSX motor. I also have the 100mm Power MAF right before the T/B and would be on the OUTLET side of the head unit.

Old setup: 350 LS1 with a D1SC with power MAF on the INLET side of the head unit

I have EFI Live to tune the car but i'm not really that great of a tuner. lol. ALL my tuning quys are at least 3-4 weeks out. Could someone tell me what to change in the pcm just to get it fired up so the money pit will stop being a paper weight? Please help!!

Even with the power maf? I think it's got like 10,000 grams or something that is WAY higher than the stock maf.

The LS1 PCM is limited to 12000Hz signal from the MAF.
That MAF may be able to put out more than that but
the PCM will do nothing with it.
