My 2006, with 15,000 miles, has so far been a great truck. It’s never in the shop, except for normal maintenance, but is there a way to make the truck "more responsive" off the line during acceleration. Now I know that these engines exhibit a decent amount of turbo boost lag, but I'm not talking about that issue. I'm talking about the engine's rate of "spin-up" upon pressing the accelerator pedal. I've read other posts where people have said that Ford programmed the 6.0s to gradually apply fuel from idle, regardless if you gently press the pedal or mash it to the floor, to meet EPA emissions standards. I know the 6.0s weren't always like this because I remember test driving a brand new 2003 6.0 (a month after they came out) and that version of the 6.0 was very responsive. I've asked the diesel techs at my dealer if this issue can be rectified and they all say that it is running "normal". Just wondering if a tuner could help.
