The MACA has had several Terminators utilize Dave Kauffman's abilities and they've all been very satisfied with his tuning abilitites, knowledge, and professionalism.
One of the best in PA, just check out www.steelcitystangs.com and search for them if you want more info. We have a dyno/tuning day with them just outside Pittsburgh this Saturday.
Thanks for your input, that makes me feel better. I have been hearing a lot of good things about them, but then again I have also heard some bad. I guess you can't please everybody!
