94/95 is the hardest. Your computer is OBD 1, with an OBD 2 connector, and some OBD features. There are a few superchips on this boards for a 94 N/A. They didn't do crap.
A member just picked up allt he equipment to write EPROMS and such, so wait and see.
Another option is customizing a Greddy E-manage system. It'll get you everything but removing your speed limiter. You can set different A/F curves for weather/altitude, run injectors up to 150% duty cycle, control timing, etc. Can be had on Ebay, piecing together and such for about $500. It hooks up to a laptop, and you can do a lot with modded engines with it.
What exactly are you looking for out of a chip? Limiter removed, firmer shifting? Straight power?
