Ford vs. Ram vs. GM Diesel HP/TQ Ratings
Looks like what many have speculated and that the 2020+ 6.7PSD is underrated for both HP and TQ. Link

Ron,
8 so has a 4.3 first gear, 10 in the 4.5 relm, compared to your 3.5ish first gear. Better starting gearing. Less pedal easier starts especially on steep grades.
I have not compared as closely on mid to top gears, possibly spaced closer, so assuming your like me, if I can't pull in OF, but in direct I could go redline, but back off to 2800 or so with past diesels, a taller ratio in trans will allow to go faster up a hill.
No one is saying per say your combo is BAD. But from past experience going from 3 to 4 to 5 to 6 and a 7 sp, when the gears are closer together, yet over all splits are wider, even with the sam motor up front, performance, mpg etc is better.
Think about how much better your current rig is vs last one with the 4 sp auto.

Marty you should set behind my wheel and tell me my truck does not launch flawlessly WITHOUT shudder. I towed my Son's 15 AISIN 3.42 at 28k combined starting on some steep grades without issue and took off flawlessly. I tow in 6th most of the time until getting into the hills. It's just not going to make a hill if beans difference.
Throw the HO 22 Cummins in my truck I am sure it would get to the top faster but by how much. Don't think I would be wishing for more gears.
