Re: sinister performance
He tuned my car and did a great job. I will defenatly use him again if I need either of my cars tuned.
Re: sinister performance
I used him as well. He is very good to work with, given the fact that I am in Colorado and he is in Indiana. Wish I was in Ohio, where I am from, then I would ve just went to his shop.
