I'm brand new to tuning. Just recieved the begginers kit from The Tuning School yesterday. I have a 99 Camaro LS1 with several modifications including: Ported LS6 Heads
Comp cams #13838R/13175R (277/288 Ad dur .627/.613 lift)
FAST 102mm throtlle body
FAST LSX Intake
42Lb injectors
I was told the stock LS1 ECM's can be harder to tune so I have a used ECM out of an 02 Tahoe.
From what I have read, I will have to use credits for the Tahoe ECM and also credits for a tune to load into the Tahoe ECM, correct? I'm not planning on using the credits on the stock ECM. The stock ECM has a mail order tune from Texas Speed but it doesn't idle at all and fuel trims are negative 30-40 (won't run below 1200-1400 RPM's.
Anyone that has a tune that you think may work well or at least be a good starting point, it would be GREATLY APPRECIATED!
