If Ford advertised 385 hp there wouldn't be anything to discuss.
The Cummins advertises 385 peak Hp and 930 ft lbs of torque. Based on what Cummins claims you'd expect it to average around 340 hp at the range of rpm it ran on a test like this.
In order to accomplish the work it did, in the time measured, it had to put 274 hp to the pavement. That is 81% of 340.
Ford advertises 450 hp and 935 lb ft. You'd expect it to average about 420 HP over the rpm range It would use on a pull like this. If it put 80% of 420 hp to the pavement it would have reached the top of the hill in 10 minutes....It should have beat the Ram by a minute 40 seconds. So something doesn't add up.
Now you are seeing why I think the truck is probably being defueled/detuned on the fly to stay within safe temps and emissions.
If your right and you very well maybe, what good is that much power if you cant access it. The 2017 GM trucks don't tow up that hill substantially faster then the less powerful 2015 truck. Certainly not as dominating as the spec sheet says it should be over the previous Duramax. They may be specing these trucks with impressive rating in order to put "Class Leading" in their advertising, but the trucks cant use it without tearing itself up. This is evident when they are run up the hill, and you find out the "Emperor has no clothes". Whatever the reason, Ford has never been as dominate going up that hill as the other two, even though it has through the years had a more impressive spec sheet. Attribute that to what you want to, but its reality.
