Apparently E85 works great in turbo motors. Didn't know that. I tried it in a N/A motor and it made it feel like a dog. Good to know
My 2013 F150 Platinum Ecoboost and 2015 Platinum Ecoboost all said no E85 behind the Fuel Door. Not sure the reason behind it but never tried it.

E-40 is safe for a start. I use it in my non-flex motors. the companies hand's are tied because of the EPA. look up Andy http://www.dynotuneusa.com/ if you want to tune for it.
As I recall, the Raptor is configured for nothing stronger than E10.
The thing with E85 is that it is both higher octane (something like 108), meaning that it resists detonation very well, and much less energy-dense than gasoline... so it takes more of it (in terms of volume) to make a given amount of power. That's why mileage on E85 sucks, and why there's no performance advantage unless a tune is configured to take advantage of the extra octane.
Tunes configured to use E85 will allow for more boost/timing than would be possible on pump gasoline, but you also must have enough fuel system (fuel pump, injectors) to move the volume of E85 required by the higher horsepower level. Additionally, the fuel lines, etc... must be made out of materials that won't be damaged (dried out) by the use of fuel with high alcohol content.
Likely, the reason that the Raptor isn't compatible with E85 when stock is because it either doesn't have or has a limited range ethanol sensor in the fuel tank.
