Sorry to bring up a few day old Thread...
Those Diesels are pretty sick when they get some work done to them. There are a few that go to BMP (Bradenton Motorsports). I dont underestimate ANY Diesel trucks any more, Like stated above one tuner gets them like 200TQ!!!! Thats Crazy!
The Truck in This Video \/ Ran a LOW13, talking to him afterwards he was upset it normally runs 12's with ease. (Cobra was 11seconds)
