03 Cobra is generally regarded as more capable because it is. Saleens are nice cars but they are basically a blown GT motor, and it will never have the potential that the 03 Cobra motor does. 3 mods I would do pulley, catback, and cai with a good tune. Those are my only power mods and I'm putting down 458rwhp 485rwtq. If you like the Roush kit, do it. I definately wouldn't flame you, and I don't think anyone else would either.
