Are there any? If so, who makes them? What could I get out of them? How much $ we talking? I am intrigued.

here'* the deal. they haven't made one for our cars but Jet chips will make one custom for us. I'm planning on getting one later this year. Call them. All they'll need some #'* from your car.

Here'* a link:

Go to the bottom right corner and click on "Contact".

Hypertech Thermomaster served me well with a 160 thermo.

With a ton of scan tool data logging or some good dyno info www.gmtuners.com can make you a chip. It'* like 40 bucks. But remeber it requires excellect scan tool data logging and or dyno info to make a chip.

yes Jet and Hypertech will be your options, for the chip. there is no full PCM available for the OBD1

That link above is incorrect. Try www.jetchip.com

Have your PCM pulled from the car before contacting them. 93 SSEi chips are off the shelf, they'll need numbers from your PCM case to burn a 92.
