Definitely a great idea. It sucks to have to drive 3.5 hours to get a dyno tune. And it would definitely bring in customers from other areas like richmond and nc.
Turbo xs only tunes for their products if I understand correctly. I know for a fact he doesn't do baseline runs, and it is closed to the public. Don't know anything about curry's. There definitely is not a 6mo. wait for altered atmosphere. I got an appointment for the same week I called (maybe I got lucky). I wasn't impressed with their facility, but maybe I had too high expectations.
