A remap changes the factory calibration, so on a vehicle still under manufacturer warranty it may affect coverage on powertrain components. Performance tuning keeps all emission systems working; deactivating emission devices such as DPF, EGR or AdBlue is not road-legal in the EU and UK and is intended for off-road, motorsport or export use only.
