Some thoughts here:
I've bought new Fords 1971. Stuck with simple, unsophisticated versions and never had issues. Always reliable and economical vehicles (mostly F100/F150, six with stick). People who bought the high-dollar, optioned-out versions of what I drove, often had serious recurrent problems. Conclusion: Ford does simple well. Ecoboost is not simple.

A small engine like the 2.3 will be into the boost quite a bit to achieve anything approaching normal road performance in a Mustang. This is obvious, no one would buy a normally aspirated 2.3 Mustang; the car is too heavy, it would be gutless. So, being into boost a lot, economy will suffer.

The 3.5 Ecoboost they put in the trucks would be a better choice. The 3.5 is enough to push the car around in a respectable manner without getting into boost, yet the power would be there when called upon. The 3.5 Ecoboost seems like a great match for the Mustang and I can't understand why it isn't offered...other than Ford enjoys raking in the big bucks on the 5.0s.

At high elevations, boost comes into its own. NA engines lose power with altitude, boosted engines don't. If I lived around Denver or some other high altitude location, I'd be sure to go Ecoboost as that would be the only way to get an engine that could deliver its rated power. Though, I'd probably go for a tricked-out 2WD, short-cab, short-bed Ecoboost F150 before I would a 2.3 EB Mustang.

Overall, I think the 2.3 Ecoboost will be gone from the Mustang line in a few years. Too little return in either performance or economy for the extra complexity of the EB engine. It will be replaced by a 3.5 or similar V6 EB that can deliver the kind of performance Mustangs are noted for without working hard.
