There's just not much to gain trying to tweak a stock late model, naturally aspirated motor. Intake, headers, high flow cats and full cat back exhaust on my old SRT10 was only worth about 6% improvement and the person who put it all on before I bought the truck spent at least 6 Grand on the parts and install. Forced induction is another story, but that's a lot more than just tuning.
