The other thing to keep in mind is from the dyno graphs, that 'dip' is ~ 85% of peak torque. The low rpm peak and the high rpm peak are very close to BOTH making peak torque.
It isn't so much that there is a horrible dip, but that the motor manages to create a LOT of torque in the 2500-3200 rpm range. (Name another 2.0L NA motor that makes ~150 lb-ft @ 3000 rpm...)

While this is true (and impressive), I really am interested in seeing how some tuning can smooth that out. Whether it is handled by bolt-ons or a remap, this would be worth quite a bit to me, as long as it is CARB legal. Fuel mileage isn't as much of a concern to me as feeling uninhibited in my shift points.
