Any advise on tuning for a procharger? Anyone have any advise where to start tuning for adding a procharger? I have a 00 TA. The only mod would be a cat back. Installing a D1SC @7-8psi with twin 3.5 IC, racetronix fuel pump and 42lb injectors if the guy ever sends them to me. I have EFI LIVE that I just bought. Plan on getting a wb o2 also. I know I will need to set up the IFR of the 42#ers. Isn't the stock timing to high and needs backed off some? Thanks for any help.

I am in the same boat installing my P1SC w/42lbs injectors. I have a 94 Camaro with a basicly stock 2003 LQ4 6.0L under the hood. here is a link to the injectors.xls file. I don't know if that will work for EFI Live?? I have Hp Tuners to tune my car. I am a tuning noob but from what I have read,
change IFR for the 42's
timing 15-17*
WOT AFR 10.9-11.1

I have the same basic setup, LQ4, 42# injectors, D1SC 7psi. I've attached the timing that I've been using. I just added meth injection and have started adjusting things again, but haven't got it right yet.
Anyway, I ran with this timing for about a year and it worked ok, but I never did dyno time to make sure it was "best". I searched the tune repository at HP tuners and found a few files there too...
