[QUOTE="smurfslayer, post: 1488200, member: 21926"] It’s hard to say, what’s the use case for each truck? I think the biggest contributor is probably the shift strategy. My early ’17 wouldn’t downshift in eco mode once moving without full throttle in most applications. Reading comments here I got my stealership to do a reflash and the difference was instant and dramatic. Instead of 10th gear and 18 pounds of boost to get up a long hill, I’d get 9th or 8th with moderate boost levels and I noticed fuel consumption was better after the flash. My stealership wouldn’t do the reflash without me reporting some kind of problem, they would simply connect the truck and report back the truck was within spec. I think that may be a contributor to what you see there with the year over year discrepancies. As the programming improves, the old trucks are damned to the old programming unless you report a problem or issue. That seems a little odd but whatever. [/QUOTE]
