Those who are 'on their turbo' will have less MPG...even running empty with
no load whatsoever

Why some naturally aspired V8's can get higher MPG, as on the high end, betcha
that small V6 eats or gets stuffed with more air than a bigger V8

The Ecoboost almost makes 1 atmosphere of pressure so under full boost the 3.5 liter is almost a 7.0 liter engine. And since turbocharged engines are less efficient than N/A engines the 3.5 Ecoboost will use more fuel than a N/A 7.0 liter engine while under full boost.

Good thing it's difficult to run at full boost for very long. After ~20 seconds from a stop your at the speed limiter unladen.
C/D TEST RESULTS:
Zero to 60 mph: 6.6 sec
Zero to 100 mph: 18.8 sec
Rolling start, 5–60 mph: 7.2 sec
Top gear, 30–50 mph: 3.7 sec
Top gear, 50–70 mph: 5.3 sec
Standing ¼-mile: 15.3 sec @ 92 mph (not bad)
Top speed (governor limited): 101 mph
Braking, 70–0 mph: 169 ft
Roadholding, 300-ft-dia skidpad*: 0.78 g
Not the rocket some want you to believe they are though.
And when your not at full boost (99.9% of the time) the fuel savings is noticable.
