Programmer, good exhaust (not just a cat-back), a CAI may help as well. Something you definitely need to get that moving with the little engine is GEARS. Do you know what your stock axle ratio is? 4.56's - definitely worth it, but a bit pricier for you to do since you're 4wd. If you can find a set of HO cams, get them. If not then you can probably get a custom set of cams ground to those specs. Then custom tuning would help you out tremendously.
