How engine tuning works on a diesel Alfa Romeo 156

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.

For reference, JTD and Multijet are the Fiat Group names for its common-rail diesel engines.
