Need help in hp

i have a 2002 firebird formula and want to boost its hp with out breaking my pocket my limit in spending is 1000 to 2000 any suggestions

Msd coil packs = improve acceleration.
Street package cams = sweet exhaust sound and hp increase (depends on package)
Hypertech programmer = 20 to 35% hp increase depending on bolt on if any on car already
Cat back exhaust/headers
And I'm sure there's more but I can't think of anymore.

Cold air intake, full exhaust, gears, ported heads, nitrous, rockers, cam, or even a dyno tune can do the trick, regardless if its stock of modified.

Id look into a cam swap, possibly a LS6 intake, dont waste you time with the MSD coil packs, they are a waste of 500$, the factorys are what the BIG HP guys are running, because the MSD's have been proven to fail many times, if you want to upgrade your coil packs, look into some D585 truck coils, but most will say they still are worth the 100-150$ they will cost you. Big things id look at are headers and a exhaust, there are plenty of companys that do some really nice long tubes for the 4th gens

Edit: Also, do not waste your time with off the shelf handheld tuners, spend an extra 200$ and take it somewhere and get a custom tune done
