Whom might suggest in the Cleveland / northeast Ohio area. It would be nice to establish a rapport with a reputable dealer / tuner. Even though I'm only 30 minutes from Summit Racing, I prefer dealing one on one with enthusiasts with honest advice based on first-hand experience.
Mike - I can only think of a few IN shops. But noone that really specializes in LS1 tuning in OH. Like I mentioned before the major tuners offer mail order tunes. Mostly for changing things like rev limiter, !CAGS, gear ratio, speed limiter, shift points, and turning off codes
