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.

"We need Cummins to comment, but the only reason I can imagine for why the transmission would downshift by letting up on the accelerator on the uphill run is because the truck would have lost some of its speed... "
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.
