About MOSTUNED

How we work

We do not distribute off-the-shelf files. Every calibration is built from your car's own software version and verified on a road datalog before sign-off. The complete original calibration is read out before anything is written, so returning to stock is always available.

We work remotely. You do not drop the car off anywhere — we prepare the calibration and you write it in your own driveway from your phone. The infrastructure that makes this possible (the app, the signing server, VIN-based authorisation) is something we built ourselves.

Encryption keys never reach the phone or get embedded in the application; they live only on our server. Unlike the common "bake the key into the app" approach, this makes key leakage a structural impossibility rather than a matter of obfuscation.

What we will not do

We do not disable protection tables. Knock detection, thermal and pressure limits stay where they are — they are the engine's fuse.

We do not sell you a stage your hardware cannot support. No downpipe means no Stage 2, even when that costs us the sale.

We do not quote numbers we have not measured. Claiming a horsepower figure before seeing your car is easy, but it is not honest. We give you the expected range after assessing the vehicle.

We do not promise what we cannot deliver. If something is not possible, or we think it is too risky, we say so up front.
