I realize the turbo while in boost is no longer in economy mode, but both trucks had similar weights pulling the same weight up the same hill, with the exact same speed and acceleration. To me that means they both required the exact same energy usage and yet one was 33% more efficient. Normally that's a gas vs diesel kind of difference with the diesel having more energy per unit along with a more energy efficient motor. Basically that EcoBoost must go rich as hell over a certain boost level.
