Both Jack and I have noticed that slightly harder acceleration gets better mileage. He's got a 5.4L 4wd and I have the 4.6L 2wd so there is definitely a larger variety. I think it is because the engineers had torque in mind when they designed these trucks. Bill usually sets the speed limiter at 120, that is what mine is set at. Look around for a track and I'm sure you can find a way for them to give you access to use it. I've got one within 10 miles and a second within 50.
Oh BTW, I'm going to move this to the conversation area of the forum where other peope may see it and add their input.
