These are the power specs for 2013 engines. I think the '15 5.0 has a little more than the '13 5.0 and the 6.2 is now gone from the F150. This chart shows that the 3.5 EB has the most HP of any of them up to 4300 rpm where the 6.2 moves ahead. If you need 200 HP to get up that hill, the 3.5 EB makes that at 2500 rpm. The 6.2 has to get up to 3300 rpm and the 5.0 needs 3500 rpm. The EB provides a quieter, calmer towing experience.
Those are flywheel specs, why not an
actual dyno as this. That is exactly how the Eco's power felt. Same climbs, same drop offs that I experienced.
Obviously in loaded situation with towing, the lower rpm build up will be better since loading is going on with the engine working to pull a trailer.
