30,000 lbs behind the Ram
Clicky The Rams time was almost exactly what I expected out of a 385 hp engine. Using the same formula the 440 HP Powerstroke should have made the run in 10.5 minutes.

The testers basically said the same thing (letting up to downshift) about the F 450 test when they felt it should shift down climbing and the truck was still in the higher gear, lower RPM's, and slower speeds.
It just doesn't make sense. You let up on the accelerator to tell the truck you want it to pull harder??? Obviously if the engine is revving high, letting up on the skinny pedal will encourage it to upshift. I think Mr Truck has been sucking in too much diesel smoke.
