All of the big three have some form of TQ management in at least one gear.
I'm pretty sure that the Dmax is only in first gear. I'm pretty sure that the pre 2013 Rams were in gears 1-3. Not sure if that changed for MY 2013. I can't recall what ford does, but I know they have it.
Since they all use similarly rated axles, they all have to have some form of it to keep parts from breaking.
Nobody can say for certain just how much power that TQ management takes away. So the comparisons are impossible/meaningless.
I would be interest in the math at highway speeds. This is what will keep the load moving up the hill with/without downshifting and/or how much it does.
TQ management is not in effect at these speeds, so the math will be accurate
