Less advertised torque was compensated by more gears which produced identical performance and fuel economy

Could be.

Or the Dmax's larger turbo is not as efficient as the Cummins' smaller turbo at higher altitudes therefor it looses more power every 1,000 ft than the Cummins does. That is more plausible than GM overstating their power numbers which would put them in serious lawsuit trouble for false advertisement.

I thought Ford's original small turbo on the '11-'14 trucks was the reason for the lack of high altitude performance, and then with the larger turbo in '15 that issue was resolved. Which is the opposite of what your saying.
