I have a 95GT with a 331 stroker. I would like to try and tune the car myself. I am not sure which one I want. I've read that The Tweecer RT is very good but difficult to figure out. How good is the PMS tuner? I really don't need anything crazy I just want my car to run good and idle fine. Its an all motor car and I don't plan on using nitrous or adding an boost.
