Motorsport-only tuning files: what a workshop can and cannot sell
Every file leaving this desk is for closed circuit, private track, off-road and motorsport. It is not a street ticket. The workshop briefs the driver. Local law stays yours.
Reviewed by the lab desk before it went live. We write files; we do not rubber-stamp brochure numbers.
Workshops ask the same thing in different words: can the customer drive this to work. The catalogue answer is no. Stage 1, Stage 2, TCU, DPF-off, EGR-off, pops — all of it is written as circuit and motorsport use. We do not type-approve cars.
That line is in the terms and on the homepage for a reason. A file that stops looking for a missing filter on a track car is a calibration for that build. It is not a product you hand over with a wink for Monday traffic.
What you can sell: a remap for a car used on a closed circuit or off-road, with the hardware you listed. What you cannot honestly sell: a guarantee it will pass a public-road test, a commute consumption claim, a promise the dealer will not see it.
The customer sentence is dull and it works. This software is for motorsport and track use. You are responsible for how and where the car is used. Want factory behaviour back? Keep the first dump or order the original-file service.
We still write Stage 1 for stock hardware. The legal wrapper does not mean the map is wild. It means we will not pretend a jurisdiction has blessed it for the ring road.
DPF-off and EGR-off exist because track builds remove hardware. They do not exist as a cheat for a test lane.
If your local rulebook forbids selling the work, do not open the ticket. BMW, Volkswagen, Audi, Mercedes — the badge does not change the sentence.
