General Motors tests and validates the genuine GM parts originally installed on it's vehicles, including the control module calibrations GM issues for use in it's vehicles. Among the many factors GM considers when validating parts and calibrations for it's vehicles are reliability, durability, safety, emissions, fuel economy, and the effect on other components in the vehicle.

Warranty Coverage
General Motors does not warranty non-GM parts and/or calibrations. The use of Parts and/or Control Module Calibrations not issued through General Motors will void the warranty coverage for those components that are damaged or otherwise affected by the installation of the non-GM part and/or control module calibration. The only exception is that non-GM parts labeled "Certified to EPA Standards" are covered by the Federal Emissions Performance Warranty.
