I am new to the boosted ls motors and new to the holley hp. here is my set up . I have an 04 lq4 100% stock minus a comp 54-480-11 cam and holley 120lbs injectors. it is a rear mount on3 76mm turbo that is intercooled.I am going to run e85 and up to 15#s but mostly around 7#s of boost I have the gm 12592525 3 bar map sensor, I was wondering how much timing to run as a base tune, and what the target a/f should be.

I am at 1500' elevation

timing map is probably close for 15#'s conservative for 7. I would make 11.7 your target (gas scale)

I will give it a try and see how it runs. We're do you think I should be at with 7#s? Appreciate the advice

And just a tip, when making changes on the timing its easier for me to make the adjustments on the small table and when you enable the large table it automatically smooths between.
