 Trustindex verifies that the original source of the review is Google. Brought my Audi S3 in for a Stage 3 tune with a bigger turbo and full supporting mods. Things didn’t start smoothly — the Falcon turbo I had fitted from eBay turned out to be faulty and smoked heavily on the dyno.Instead of rushing the job or giving me attitude, they helped me swap it out for a proper Garrett PowerMax and carried on professionally. Then I ran into fueling problems caused by another low‑quality eBay part, and again they took their time, diagnosed the issue properly, fixed it, and made sure everything was right before continuing.After all the setbacks, they still mapped the car, spent a lot of time on it, and didn’t charge me anywhere near what the work was worth.They showed patience, honesty, and real skill. Very happy with the service and the way they looked after me.

This is the second time I have used Onyx Performance first time for wheel refurbishment and last time for remap and i would use their services again in the future without a doubt. They are very knowledgeable about what they specialise in, they are polite and you can see they care not only about what their customers want to do but also about what they can offer the customer. Thanks to the OP team.

 Trustindex verifies that the original source of the review is Google. Took my Mercedes C200 to Onyx performance for a stage 1 remap, my car is much quicker and throttle response is much better than before the remap. They also advise you about power and gains and the maps are tailored for your specific car and model, no stress on engine or gearbox. Thank Onyx , Brilliant work.

Frequently Asked Questions

A mileage stopper (or blocker) is an electronic device that prevents your vehicle from logging mileage on the dashboard or ECU while driving. It is mainly used for dyno testing, track days, or off-road use.

Which vehicles can use a mileage stopper?

Mileage stoppers are available for high-performance, luxury, and modified vehicles, including brands like Audi, BMW, Mercedes, Lamborghini, Ferrari, McLaren, Bentley, and Range Rover.

How is a mileage stopper installed?

Installation is typically plug-and-play, requiring no permanent modifications to the car’s electronics. Professional installation ensures your vehicle’s systems remain intact.

Can the mileage stopper be switched on and off?

Yes — most modules allow manual activation and deactivation, giving you full control depending on whether the vehicle is on a track, dyno, or public road (off-road use only).

No — these modules are intended solely for off-road testing, track days, and performance tuning. Using them on public roads may be illegal.
