Can any joe blow do this? I know very little about cars. Want to learn. Am very interested in learning how to tune my own car, but don't know where to start? I don't want to buy this program and then not know how to use it. Where do I get the info on where to start? How do I learn how to do the tune? Would be willing to take a class if that would help! Any suggestions welcome! Or should I not even try it! thanks.
