Chips ended in f-bodies in 92, so you need programming. To do it your self, you need a laptop, software, and a cable. Software can be free (Tunerpro), or bought (LT1 Edit, Tunercat, etc.). Need definition file (EE, also free). Better read and learn a lot before going this route. I can give you a copy of the factory tune and the EE definition file. You can download Tunerpro, just google Tunerpro.
Can buy a “mail order” tune. Look up madz28, or pcmforless. Both are pretty well known for LT1 tunes. I had a madz28 tune in my 94 ta, was pretty good.
Take the car to a tuner with a dyno (dyno tune). Best route, but most expensive. make sure they are using a wide band o2.
