A performance "chip" changes how the engine control system deals with the fuel, ignition, pollution control etc.
ClaimsMost claim improvements in fuel economy and power.
Most do not work to any measurable degree.
What they actually do.The vehicle computer is set to provide long term safe operation, fuel economy and to assure that the car meets pollution control requirements.
The "chip" erodes the margins that protect all these including how long the engine will last.
The "chip" will also change the settings so that premium fuel is required, as North American Premium Fuel is normally 91 octane and European fuel is significantly better sever engine damage can accrue very quickly.
ScamThe scam ones will cause a sensor to report the a changed or incorrect value, this will for a short time change the system to cause the improvements, the engine computer soon learns the new readings and adjusts your engine back to safe and low pollution operation.
