To be clear, I'm sure not dismissing what you are saying. The Ecoboost has been a great success for Ford, for sure. AFAI recall, they do some very interesting things with lowering the compression and raising turbo boost while managing with sophisticated electronics.
I've not driven any of the "small diesels" in the Big 3 half tons, and I've only driven Ecoboost half tons empty. It would be interesting to compare the "seat of the pants" if pulling both to rated loads with those half tons. (1600 vs 2500 rpm is meaningful but how does it translate??)

Either way, that hasn't translated into the heavy duty pickups, which is what all of the members here will be driving. In the HD class, the competition is between NA gas engines vs turbo diesels. Between the inherent strengths of a diesel engine for pulling and the addition of the turbo, it's not a fair fight for the gas engines
