The way I understand these tests is that they simulate driving up a grade, that is up to 6%, using throttle openings that will keep the empty vehicle at 65 MPH. Since we are discussing tow vehicles, testing an F150 Ecoboost fully loaded with a large, heavy, high profile trailer up a 6% grade on a hot day might give some meaningful information. Of course knocking and timing adjustments would be considerably different between fuels causing a much larger spread in horsepower and fuel usage.
Okay, well then go get an Ecoboost and test it in those conditions and report back what you find. Although, it will be no different than what we have stated that you will have less power with the regular octane fuel since it is pulling timing. However, even at that lower power rating, it still pulls heavy loads just fine. Until then, we will stick with the info we currently have along with our real world experiences as Ecoboost owners.
Sorry, just thought you would want some common sense input.
