Air intake, headers, full exhaust with high flow cats, TBI spacer, a set of roller rockers should gain a little power. Not sure what your budget is or the vehicles intended use.

the hand held programmers are pritty limited , i would try looking to see if its possible to lap-top tune it. for example hp-tune or ls1-style tuner if u do find one and someone in your area that knows what their doing , u can head/cam it with impressive numbers.

other than that there are also companies witch u send your computer unit and they tune it to the mods you have , not as good because if you make future upgrade u have to mail it in ext.
