You cannot take the reading of a chassis dyno to establish optimal shift points. Even more error when using a roller dyno (the 4 wheel dyno used by MT makes it even worse). The shape of the power/torque curves is altered due to losses (mostly tires rolling losses) and inertial impacts.

You should redo the exercise using the official power/torque chart published by BMW.
