Look at the description.

I ran wills tune (still am actually even though I modded further) with a near stock car that only had a intake, tstat, plugs and that's all and noticed quite a difference and had about 6* knock and after wills tune had 0*.

Just contacted him last week do I can have the PCM retuned for the cars current mods.
