I bought my 2010, used with 27k, from the dealer on sept 22. Not sure if I would have the newest flash. Once in a while the truck feels like it defuels HARD, It only seems to do it when I really roll into the throttle. Not during WOT, or light throttle.
Could just be my imagination, but it really seems to do it when its shifting from second to third.
I thought it was just the way these trucks drove.

Mine does it a sometimes and I don't have the latest reflash. For what it's worth, I test drove a used V10 with very low miles before I bought my 6.4 and it did the same thing.
