Don't waste your money on the 1 tune fits all hyperjunk. If you disregard my advice, make sure it isn't vin locked.

A better PC based tuning program for your 94 would be TunerCat obd 1 tuner. For about $100 you can get the program with the needed $EE definition file.

The only other thing you'll need is an 12 pin GM type obd 1 cable that goes to usb port of PC based computer. You can get a cable at the following site.
Thanks for the fast reply and helpful info!
