I don't know why people care 10 pages worth (to date) about a Cummins being 2 seconds faster than a Powerstroke up an 8 mile climb pulling more than most of us will ever pull. I'm sure the Duramax would be right there with them if it was rated a little higher too. From a towing performance standpoint you really can't fault any of the diesels and that's been the case for quite a few years.
A couple seconds make ZERO difference. What is very interesting is RAM PULLED THE SAME with much less advertised HP.
But with essentially the same torque. The drag race where the Power Stroke was able to achieve higher rpms is where you seen the higher HP.
Bottom line the higher HP Power Stroke is a much better daily driver and towing up a major incline the performance is essentially the same.

The thing is that the Ford didn't pull at the higher rpm because the HP wasn't there. Miles 1, 3 and 6 are not real steep. 450 HP is more than enough power to pull that trailer up those sections of the hill at 2800 rpm in 4th gear.... 2800 rpm in 4th is 55 mph. The steepest sections of the hill are miles 7 and 8. 450 hp is more than enough power to pull those sections at 2800 rpm in 3rd gear. 2800 rpm in 3rd is 42 mph. So even if the other three miles were pulled in 3rd gear revved to 3000 rpm the truck would have been going 45 mph for those sections. The Ford should have been able to reach the top in 10 minutes. This is assuming that 80% of the Powerstroke"s power could be transmitted to the pavement which is what the Ram apparently did.
