I have a 2000 camaro ss stock ls6 (gm crate). slp long tubes cold air lid maf. diablo programmer. downloaded the tune and havent really noticed any difference. any advice on power enrichment or timing advance. thanks god bless the ls

 

What MAF is on the car?
These tunes are designed around a stock/mildly modified cars. The longtubes and non stock MAF likely need some tweaking to take advantage of the changes.

If you have the stock MAF, try putting that back on first.
