96 sunfire, wondering if there are any performance chips out there for it.

Well for the research Ive done and with no finds to be proven, Only performance chips that work, Are the 87-94 cavaliers, Others no success, If youre looking for performance gains, Cold air Intake w/ K&N cone filter, 4 in 1 pacette header Catback exhaust,If you want to add more power Ecotec motor swap, In which that will run you to $2200-2500 swap. Or add some forged pistons in youre current motor add a turbo Or super Charger. Heres also some links for you to check out:
