I think you just explained why the CUMMINS does NOT need more than a 6 speed.
You're happy with how your Cummins pulls with a 20% torque rise. The HO 2021s with a 36% torque rise have much less need of more gears.
Looking at it from a little different perspective a person could argue and say "With enough horsepower torque rise is a non issue". And that statement is true also. If I'm pulling a 17k RV up a 6% grade with my Powerstroke at 60 mph, the transmission will drop into 6th gear. In 6th gear my engine will be running 2500 rpm where it is capable of making 460 horsepower. 460 horsepower is enough power to pull my trailer up the 6% grade at 60 mph. So, in this scenario as my truck starts to climb and more torque is needed the engine doesn't slow down ... it holds 2500 rpm as I continue to feed it more coal.
