We now know that the '17 truck was slower due to transmission gear selection/gearing. It was slow from the start so defueling was not the issue like you were mentioning back then.

Right. Is that the same thing that happened in 2018 when they towed 28.5k on the same day(in hotter weather than 30F)? Rated at 65 more horsepower, the 450 hp PSD that got 11:43 should have mopped the floor with the 385 hp Cummins that got 11:41.

Like I said, tow the same trailer in the same condition at temps above 60F or 80F and those high power levels cannot be sustained like they can in 30F. Although the 2020 does have the edge with the 10-speed.

EDIT: Although I will say that a trans not holding gears or shifting too much is a good indicator that the engine is defueling.
