You're correct. I spend most of my time on the highway (and mostly at or above 80 mph). My thought on going to 4.56 is because my auto trans is five speed. I would like all of my passing and acceleration at highway speed to be with a downshift to 4th gear. But to really "kick it in the guts" and push myself back in the seat I need to downshift to 3rd gear and let the motor spin up to 3,500 rpm and stand on it through 4,500 rpm and then either lift off the pedal to shift or use the auto-man to up-shift. I would hope that the lower gears would get the rpms up just enough to get have a bit more available power at the pedal in 4th gear.
