2004 2500HD LLY Max/Allison w/Edge and Attitude, 11,500 miles, crew cab/long bed - nothing quick about this truck coming off the line for approx 5 seconds, then the chip kicks in and it raps. While I'm not a hotrodder, not even a chirp from the tires unless I go thru water. Hook up the 40' weekend warrior 5th wheel and the hesitation becomes a major issue - slow easy takeoffs are no problem. But try to accelerate thru a left turn and it's fill-my-pants time - when the truck is thru the intersection (obviously there's 40' behind me that's NOT), the chip kicks in and the trans can barely keep up, with hard chassis-jarring shifts thru 2nd and 3rd gear. I wanted a 7.3 Pwrstroker but Ford changed to their own lousy 6.0, so went to the Max. Dealer says it checks out within specs. On the road, this thing rides great, has plenty of power (except an occasional hard downshift - glad I bought the warranty), and unhitched gets 25mpg at 77 mph. HELP!!!
