How engine tuning works on a diesel BMW 5 Series
The gains from remapping a diesel come from the engine management software rather than new parts: injection, boost and torque limits are re-mapped, which is why torque improves most and why the car often feels easier to drive at lower revs.

Ranked by power gain against the other diesel 5 Series engines (17 in total), the 5er E39 520d 136 is 4th, exactly the 5 Series diesel average.
