I can recommend Hitman to anyone here! He beats other people on the list above (both what i've heard and experienced) and is always willing to explain anything he is doing or answer any questions you may have. He does do mainly road tunes, but for the cost of hiring a dyno, he'll dyno tune as well. He spent about 4/5 hours on my car, just tuning to pass an emissions test...i was very impressed!! Just an example of how through he is....
He was at the cruise on friday night...i'm sorry i didn't do a good job of introducing him around! He is also on the forums (Hitman) so i guess PM him with any questions?
