Can a vehicle be re-tuned for maximum economy, or is this what the manufacturer's do already?

I have a 2016 Ford Transit passenger wagon with a 3.5L twin turbo gas engine that produces more power than I need to hauls people and an occasional small camper. In exchange for that power (and because it's an aerodynamic brick), I get 16 MPG. I am wondering if it would be possible and cost-effective to re-tune it for fuel economy. For example, the Ford Expedition has the same engine and is similar in weight, but has a higher listed mpg. Is this all aerodynamics?

I've seen re-tuning costs hundreds and therefore I'd need to save at least 3 mpg since I drive under 10K miles/year.
