I also have an automatic GT, and have gone the "bolt-on" route. Meaning I have done all the little things to increase performance, like exhaust, gears, chip, etc etc. If I were back in my original position, though, as you are, all I would do would be slap a Vortech Supercharger kit on it, get a good dyno tune, and finish off the combo with a cat-back exhaust and some Drag Radials. It may be costly, but trust me, this is THE best way to achieve good performance easily.
