Theres also Cincy Speed in Cincinnati and Modular Depot in Northern Kentucky. Seems like there might be someplace in Dayton but I can't remember off hand. Is there no place in Columbus?
Get a dynotune, not that much more than a mail order tune - with that combo it'd be best. I'd also recommend Big Shot Dyno. I tune cars but if I did not, I'd take my own car to Big Shot.
