What a remap does for a diesel Mercedes S-class

Nothing is bolted on in a diesel remap. The ECU's stored maps for injection quantity, rail pressure and turbo boost are rewritten within safe limits, and because diesels make power through torque, that is where the improvement is most obvious.

For reference, CDI is the Mercedes-Benz name for its common-rail diesel engines.
