True that. GIAC has better performance gains too from what I've seen.
I had the option to do that, but decided to just drive to Chicago and let them do it there. (Its a different place that just happens to be in Chicago also). It is a cool idea but it takes longer since you have to log, send logs, receive tune, rinse, repeat. I prefer to have the tuner in my car, actually doing it hands on. Also keeps me from having to top out 3rd gear on the street to get some logs.
