Today I had to drive a friend of mines new 6.0 powerstroke. It is a F-350 crewcab 4x4 dually 4:10 gears. I was pulling my 6 horse trailer with it and not to say good about ford but it blew me away with the power. On the side of a hill where my truck would have to redline to pull ithis truck was just cruising in 5th gear.Even with the air box and hypertech my truck [02 3500 crew cab D/A 4x4] would not be able to stay beside his stock truck.Please dont hate me I just wanted to share what I seen.Chevy needs to make the allison put more power on the ground before down shifting and burning the fuel. Have any of you guys drove one of those trucks and what did you think?
