Exactly right. As far as I know, EPA test has a predetermined schedule of speed and acceleration. Since the base 3.7L V6 can accelerate fast enough to complete the test, it's doubtful the EcoBoost needs much boost, if any at all, to produce the needed power. Hence good EPA rating almost as good as base engine.
On the street drivers with more power will use more of it. Hence more fuel. Maybe that's why Ford developed a smaller 2.7L V6 Eco-Boost for the new F-150. I'd guess that will eventually filter down to Transit.
