I can definatley agree with firestang70. I would highly reccomend MD in the Cincy area. I visited Ken's place just yesterday and he is a great tuner and a great guy. He is very easy to work with and very patient when trying to make the most out of your tune. He impressed me by trying to show us what all he was doing to make things better, but me looking at the tuning software was like me reading greek. You will probably need to call and make an appointment, he was very busy yesterday.
