I'm in brooklyn and sans Mustang yet, but have also been looking for a place and ran across Mustang Magic. I was going to paste the link but you beat me to it!
Do you have personal experience with them? Pretty good? If I go in with some parts and ask them to install 4.10 gears, an X-pipe, axel-backs, a CAI and pulleys, and then to throw her on a DYNO and give me a custom tune, can they do all that? If they're doing work and DYNOing, are you allowed to hang around and watch/help?
This will be my first time modding a car (first new car, first performance vehicle, first car I'm buying) - would like to find a trustworthy and skilled one-stop shop (if possible) who can help me tune it and will let me watch, so I can learn a little about this stuff (have already learned a lot from these boards).
Thanks!
