Horrible high elevation
Just wanted to add on here I've been doing researching on my 14' 5.0l running like complete S*** up here in colorado. Ive been here 3 days now and it still hasn't adjusted itself. I live in Oklahoma and am on vacation here in Colorado at 7,500 feet above sea level and the truck won't downshift when floored, the power when accelerating is cutting out a little its just disappointing to have a brand new truck that can't adjust to the elevation. Im glad i don't live up here but wish ford made it work better at higher elevations. My 11' Eco boost ran like a beast in Colorado and Wyoming! got like 22mpg all the time even driving the **** out of it. Only good thing about the Eco in my opinion is that the turbos love the air up here. Anyways I'm done bit****.
Thanks Guys

That's the major downfall of an NA engine. You could try a KAM reset to allow the engine to learn the fuel trims to the elevation quicker.

Think he is wrong on the power loss though . . .

It's not clear exactly how much compensation the PCM actually does based on barometric pressure without unlocking and reverse engineering Ford's PCM code and tables, but it is not nearly as simple as '1% loss per 1,000 ft.
But the short answer for the OP is 'The EcoBoost absolutely ROCKS at high altitude...' It leaves Raptors and F150's with the 6.2L's huffing and puffing in it's dust, let alone the 5.0 engine.

Ecoboost uses a MAP sensor, stands for manifold absolute pressure, as in not relative to atmospheric pressure. As long as the turbos have the capacity to maintain a constant MAP pressure, the HP should stay the same.
