An advantage to a forced induction motor like the Ford eco boost, a majority of dusel motors, is the fo not lose HP at higher elevations like a natural aspirated motor like the GM V8,s, Ford's 305 etal. They lose 2-3% ofHP per 1000' above sea level you go. So at 10,000' like you are at highest points in Yellowstone as an example, that 6.2 is down some 30% hp, the turbo version is still cooking along at potential max HP.
I took the same trailer, etc thru Yellowstone with a 454, 9 years latersame trailer, older teens about 1500 total lbs heavier with a GM 6.5 turbo with 50 less HP, it smoked the 454 going up the same 15% grades at 9-10,000' that the 454 could not do but in 1st gear ofits 3 so auto. The diesel with 5 gears, di it in third, or equal of 2nd with the auto. 10-15 mph faster.
Having a turbo at elevation helps.
