That's weird, with those mods your truck should be putting down more power. But the dyno could be off.... that's one of the main problems with dyno's that the public can run on now. They aren't calibrated properly...
Yeah, we are talking about approx 200 HP difference, just thought it might translate a little better to the pavement even with the increased weight. I used to drive for a moving company, my truck was a 379 peterbilt with a c15 cat motor and 13spd, I think around 475 HP and that things wasn't quick in the least but man could it pull. I understand the workings between a diesel and gasoline (at least it makes sense in my head
) I just find it amazing how the power band/curve or whatever it is referred to can vary so much and affect acceleration that much.
I agree with the mods and getting better numbers out out than you did, I don't know if environmental factors can influence it to that extent.
