That is around 30% increase in HP in two years and well over what the 6.7 Cummins and the Duramax has NEVER achieved even in 15+ years of production!

You mistake "can't" with "won't" here.

The Big Three are in a figurative poker game with their big diesels. Nobody is going to show the full capabilities of their engine, for fear that the other guy has a better engine. They keep some HP and TQ in reserve so that whenever someone raises the bar a little, they can keep up.
