Anybody have a LT1 edit file for a car with LT headers, CAI, 1.6 RRs, ORP, catback that I could look at the A/F and spark curves?

 

you can get a better idea of ideal AFR in PE by asking in the LT1 or LS1 sections. Many opinions on that one, however, it has been show that high 12's are best.

As for timing, this is an area not covered by many people because it is difficult to get the best timing in our cars without being on a dyno. Do a search and you will find some good info on this one. I certainly would not trust anyone else's timing map within my car and I can suggest you feel the same.
