Brett at XP Racing on OKC did my boosted 01 car and I plan on going back when I make some changes. I also had a guy in BA do my LT1 car and I would recommend him as well. He tuned while I drove and did it really cheap. He's a great guy. Let me know if you want his info. There are several others around that do tuning and have fairly good reps. I'm sure others will chime in with their info, I just dont have any personal experiences with the other tuners around here.
