Diesel BMW X3: what changes with a remap
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 X3 engines (5 in total), the 3.0sd 286 is 5th, 1 bhp below the X3 diesel average of 36 bhp.
