Yeah, I know.....me too....
Although I will say that I towed our 28 foot TT many thousands of miles last summer on regular fuel, and up to 7,000 feet altitude on some mountain passes, and it seemed to do fine...definitely am going to have to try 91 octane for towing this summer...maybe I CAN get better than 8.5 mpg!!!

Ford's timing tables from 2011+ vehicles on are EXTREMELY aggressive. The engine management will increase timing until it senses knock, and then pull back. Then keep on doing it until the most hp is achieved (along with other variables).
I see no reason why this isn't at least plausible if not true on the F150's as well.

People actually put regular octane in thier EB? Always thought that this engine required premium fuel, as with all other turbo engines usually do. That just the way it always been for me; if it has a turbo or s/c, it needs premium/ higher grade fuel.

Nope. The Eco is built to run on 87. It just runs a bit faster on 91 :-)

It's not plausible for the 3.7's. It's a fact. 93 octane in the Mustang motors, both 5.0 and 3.7 will net you more power.
I have no doubt it's the same for the trucks.

I know that 5.0 Mustang talk is a bit off topic here but one of the major Mustang tuners did a dyno run of a 5.0 on 87 octane, drained the tank and then ran a 93 octane dyno run. The 93 octane gave it a 10 horsepower increase.

They did it with the N/A 3.7 Mustang AND the 5.0.

Wow that is some smart engines
