I'm just far south of it right now... there's no way it takes even close to 265 lbft to move that truck at 60 MPH. Not even close, considering that it takes less than 20% throttle on a flat to maintain my speed. I can pull a 4-6% (According to the last land map I saw) grade at 20-25MPH in 5th gear without downshifting, as long as I don't let the RPM's drop much below ~800. I usually pull that hill in 4th, though, just over 1,000 RPM.

For some reason, I feel most comfortable with the truck at ~1,000 RPM.

I think I could get a pretty nice gain by halving my cruise RPM, though, especially if I use the splitter to accelerate and skip gears. I can keep the engine loaded better if I skip gears, and having the splitter will keep the engine loaded better under acceleration (not that I do that much of it).

My peak BSFC (theoretically) is probably going to occur somewhere around 80% load at or slightly above 2,000RPM, provided everything is working correctly. I can guarantee that at less than 20% throttle, I'm so deep into the area under the curve that I'm pretty close to running rich, despite the OBD-II system installed, and the EEC-V ignition control system.

Under the average circumstances, I think you're pretty well correct, though.
