How engine tuning works on a diesel Alfa Romeo 147

On a diesel the ECU decides how much fuel is injected and how hard the turbo works. A remap adjusts those calibrations within safe limits, so the gains show up mainly as extra torque low in the rev range and smoother, more responsive pull.

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