With the narrower ratios of the 8HP70, I too would think that going right to the red-line may actually cause more of a drop in rear wheel torque available than dropping down solidly into that much stronger, flat-rated mountain top of torque in a numerically taller gear.

Anyone have a torque plot of the 50d N57?

This is the best I can do:
Power and Torque curve for the 50d.
