Chip Tuning (Engine Remapping)

It alters boost, fuel and ignition maps. It may affect warranty and insurance. Some tuning is not road legal. Tuning should be done by reputable specialists who check engine condition first. Some countries require registration of performance changes. Before buying a used car, a scan tool or dealer check can sometimes reveal modified software. Returning a car to standard software is often possible if the original file was saved.

Modified maps change how the engine is controlled.

Extra load can damage clutches and turbos. Emission compliance must be kept.
