Ok I've heard many people talk about many places that do great work, and then I hear other people say that they do bad work. I'm just about finished with my car and the last thing I need to do is to have my Haltech tuned and the car dynoed. Does anyone have personal experience with any shop that they have dealt with personal not heard it from a friend. I've been told DRT, Pruven and ECP but again have heard good and bad things about them.

Thanks
