You know, it couldn't be too much hassle to drive from PA down to Intense in OH and get them to retune your car. Especially since when they do it, you don't have to buy HP Tuners and retune to support a 3.4" pulley. Then all the other mods you do from there will only help, like headers and such. Sure, it helps to retune for that, but it'* just so you can get more. Tuning then isn't needed, just desired because it gives you what you can't have with stock exhaust manifolds, for example.
