Off-road & motorsport use
Some operations we offer are not legal on public roads in many countries and US states. Please read this before ordering.
Modifying, removing or disabling emissions-related systems — including DPF, EGR, SCR/AdBlue, catalytic converter monitoring and related diagnostics — may be prohibited for vehicles used on public roads. In the United States this includes federal rules under the Clean Air Act as well as state regulations.
Our policy
- Emissions-related operations are supplied only for vehicles used exclusively off-road or in competition.
- By ordering, you confirm the vehicle will be used in line with the laws that apply where it is operated.
- We may refuse any request we believe is intended for road use.
Performance calibrations can affect manufacturer warranty, insurance and inspection. You are responsible for checking local rules before fitting any modified file.
