The best way to start, is with the basics!

All the Free mods.....THEN!

Intake system, pcm tune, 180* Tstat, PEM's (ported Exhaust Manifolds), 3" DP(DownPipe), and then I would scan for knock. if there isnt any...I would drop down to a 3.4 pulley. and then rescan for any knock.

that would be a baseline..... then after how far do you want to go with it? how fast? what is your budget? what are your plans?
