Here's the deal.
You want to go up a hill fast in tow? You have to make the most HP your engine can put out. With that little Ford you need to wing the thing to make the most HP.
People really need to stop worrying about RPM. "ALL" throttle by wire engine have NO red line. It's all regulated by the ECM. It's not like the dinosaur days where you had to watch your tach or you're going to blow up your engine by too many RPM's.
Just to give you an idea of how little you're winding your engine: I have a 9.4 liter engine that I shift at 6,900 RPM. That engine has pistons as big as coffee cans. It's designed and built to wind that high and your little engine is built to wind 5,500+ RPM to make it most HP.
Even then, your little engine does not put out that much HP. Depending; it makes low 200's to high 200's. Get it up to 6,000 to 8,000 feet and now it's making High to mid 100's. That's not much HP to do much of anything.
In short: Plant your right foot to the floor until you get to the top of the mountain. :B
