What a remap does for a diesel Alfa Romeo 166
Diesel engines respond strongly to remapping because the ECU controls injection quantity, injection timing and turbo boost pressure. Re-calibrating those maps typically brings the biggest improvement in mid-range torque, which is what you feel when overtaking or towing.
For reference, JTD and Multijet are the Fiat Group names for its common-rail diesel engines.
