I think the 35 MPG is a lot more believable than the 1200 hp. Dave is getting 27 out of his super duty and trucks are bricks with huge frontal areas.
For those of you who know nothing of modern performance diesels, the things that they do to make more power also make them more efficient as well, such as advancing the timing and increasing the injection pressures and diesel already run very lean under light loads. Because diesels effectively knock to run they are not octane limited, you can keep pouring the fuel in as long as you can supply enough o2 until they bust. There are more than a few 800 hp diesels on the street from the big 3 right now.
