A buddy of mine owns a speedshop that he just acquired recently when the old owners sold it. Well the guy who used to tune all the cars at the old shop taught one of the new guys how to tune and what to do and everything. My friend blake who works up there part-time says he let them practice the tune on his car and he loves the way it feels. He said they would do mine for free, because they want to do it on all of their friends cars to get experience. So what do you guys think? Should I get it done for free? Is there anything they could mess up? And if I didn't like it, could I get it back how it was to begin with? (he told me they could return it to normal if I didn't like it..)
