How ECU tuning works on a diesel Peugeot 407

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, HDi is the PSA name for its high-pressure common-rail diesel engines.
