Gt power

I have a stock 97 grand prix gt. what are some cheapish things i can do myself mods?

u-bend delete, hi-flow cat, cold air intake/K&N type air filter, reprogrammed PCM (will require use of premium fuel), and if you're not afraid to take the valve covers off and tear into the top of the engine, 1.7 or 1.8 ratio rocker arms.
