There is no way a turbo gets 100% or even close to it.  Do your math.

How many 6 cylinders pull a 5 second 0-60 MPH? ZERO. Not even the new supercharged 6 cylinder Audi S4.

There's no secret here- ITS AT THE LOVELAND PASS! Of course it's at altitude! So what?

Excellent video.  Make no mistake the challengers are missing one key component at a elevation of 12,000MSL.  

At 12,000MSL, this altitude the air is very thin; any naturally aspirated engine will be suffocating for air to feed those cylinders.  As a result these engines are not nearly performing at peek horse power.

All this gives the Lincoln w/ EcoBoost the advantage, as this is no longer a naturally aspirated engine.  I could go on about how the Lincoln's EcoBoost (turbo) lowers the pressure in the cylinders by compressing air and giving it more horsepower etc.  

In short Ford's EcoBoost gives the engine 100% (or close to that) power from Sea Level to Mountain Range altitudes, whereas the challengers don't have that option and suffer the horsepower at higher elevations.
