I am a couple weeks away from purchasing my first mustang. It's a 90 musang gt with 75k miles and completely stock. What i had a question about is that it has never been on a dyno and i was wondering what should be done to get in top shape for a couple dyno runs. I want to put down some stock numbers as a baseline so i don't really want to do anything major to the car. I've heard a tune-up would be good to do and i will plan on doing it and since this is my first car i am not really fimialar with al that is involved in a tune-up, can someone help me and just give a list or something of all the parts? i know a plugs, wires, but thats about all i know of at this point. And any other suggestins on anything else that could help me out.
