That's the thing with an EcoBoost. You can only have one. Eco, or Boost. Your right foot chooses.
Could not the same thing be said for virtually every internal combustion engine with a throttle ever built? Would a statement like " you get to choose one" be more accurate?
To some degree, yes, every engine uses more fuel as you push them harder. But gas turbo engines are the WORST.
The main reason is that forced induction gasoline engines run very rich when pushed, to cool the air/fuel mixture, thus preventing pre-detonation and cooling the EGT.
A diesel on the other hand, is the exact opposite. The LEANER a diesel runs, the cooler it is (in terms of EGT).
NA gasoline engines are somewhere in the middle, not nearly as lean as a diesel, but not pig rich like gas turbos.
In conclusion, if you're doing high duty cycle work, diesels are the best, followed by NA gas, then turbo gas, and possibly supercharged gas as the last resort.
