My sincere appreciation to tony martino at ridge runner diesel and henry at creatures of the night. I talked to tony about his tunes on 2 separate occasions for over 40 minutes at a time and then ordered them at 8:30 at night and got great customer service at all times. Henry did his best to help me out and then referred me to the source, tony. Can't wait to tune my truck but for anyone looking get in on the summer sale and enjoy the customer service.
