I notice you live in Denver, does the ecoboost seem affected by the high altitude? I drive a 99 F150 w/5.4 and moved close to Denver from PA. The first thing I noticed was the power lose from being 5k above sea level. I also was getting 18mpg in PA (truck is not stock) but living in the Denver area I barely get 15mpg. I wonder if the ecoboost, 5.0, and 6.2 will experience this type of power and fuel mileage loss.

Pasted from an online article after a simple Google search:
The high-altitude performance of a turbocharged engine is significantly better. Because of the lower air pressure at high altitudes, the power loss of a naturally aspirated engine is considerable. In contrast, the performance of the turbine improves at altitude as a result of the greater pressure difference between the virtually constant pressure upstream of the turbine and the lower ambient pressure at outlet. The lower air density at the compressor inlet is largely equalized. Hence, the engine has barely any power loss.
