Hi all -

Ive got a few tuning questions...

I have a 2002 Z28 with headers and other mods in sig. (Using a stock MAF)

To get my LTFTs into the -1 to -4 range, I had to scale the IFR by .88 is that too drastic? Does this mean that I should be able to lean up my PE and A/F by 12% now?

So far Ive scaled my PE by a blanket .96 and the A/F was blended with the higher MAP and RPM cells getting .96

Also, Ive scaled my spark table to have a maximum of +5 (which is 24 vs the stock WOT 19) Does that sound about right?

If I go any leaner on my PE and A/F i get some audible ping. Right now Im not get much if any KR. I know I cant tune by stock o2s but theyre reading .935 right now.

Am I doing this ight so far? What have you guys with headers only cars done?

Thanks,
-Tony
