Emissions & legal use

Tuning capability and permission to use it are not the same thing.

Last updated September 13, 2026

Comply with applicable law

Vehicle modifications and calibration changes are regulated differently by jurisdiction and vehicle use. You are responsible for confirming that a product, feature and calibration are legal for the vehicle and its intended use before installing or enabling them.

No authorization to defeat emissions controls

gpecPRO products and services must not be used to tamper with, bypass or render inoperative emissions-control or safety systems in violation of applicable law. Product capability does not establish legal permission for a particular modification.

Ask before purchasing

Vehicle support and legal use are separate questions. If a description does not clearly establish compatibility or permitted use, contact gpecPRO and consult the rules that apply where the vehicle will be operated.
