Before you go looking for a tuner, put your car on an obd1 scanner capable of showing real time sensor data. If you don't have such a scanner, you can download a free obd1 scan program made for 94 & 95 f-bodies. It's in the 4th gen section. You will, however, need a laptop or notebook and a cable to connect car's dlc to usb port. Get cable at
ALDL OBD1 OBD cable OBDI OBD2 engine codes get the 16 pin model.
Other scan program options are freescan, if you want it pm me with your e-mail address and I'll send it to you.
Or you can download the trial version of DataMaster good for 20 free data scans and unlimited data playback. It's a good program because you can playback the data you recorded in real time, as many times as needed. Get at
TunerCat
Also if you need it, I can send you "scanner readings and what they mean".
A tune would not be needed unless you have modified the car, such as cam, headers, etc.
