Easy.... max vacuum!   oh shit, that's another can of worms.

So here's a topic to make you think: We know that an engine's torque typically peaks well before the redline - the conservative engine speed limit where mechanical bits misbehave. And if that point on the torque curve is where the engine is making maximum twisting force, where should one shift??? I believe the answer is to maximize the area under the torque curve, the integral of torque from i to j. That plays into gear ratios, ratio spacing and of course, your choice of shift points - i and j. Whew!
