Stage 1 Remap

Factory ECUs are deliberately conservative. They're tuned to work across different fuel qualities (super vs standard), extreme climates (Sahara to Norway), poor maintenance, and hard driving by owners who don't understand their cars.

The manufacturer builds in a reliability margin — headroom in fuel mixture, boost pressure, temperatures. Stage 1 tuning uses that headroom. We keep your turbo, intercooler, fuel system, and cooling system exactly as the factory designed them.

We work within the hardware's safe operating window. Your engine won't run hotter, your turbo won't spike higher pressures than its design rating, your fuel system isn't overloaded. You're using the capability that was already built in.

On-site: typically 1 to 2 hours. We need the engine warm for proper sensor reading, OBD connection established, calibration written and verified, then a short road test to confirm everything is right.

Bench remapping is available for some ECU types — we take the ECU to our workshop, read and tune it offline, then reinstall. This is less common but useful for vehicles with difficult access.

For most diesel and petrol vehicles, the mobile on-site service is the standard approach. Quicker, safer, and you can verify the work immediately.

Some cheap tuning operations flash a generic file to hundreds of cars. That's not how we work.

We read your car's specific ECU. Every vehicle has its own software version, which can vary between build weeks at the factory. We tune your exact calibration, not a template.

This also means your tune is unique to your vehicle — if you sell the car, the new owner doesn't get your setup unless you arrange a transfer (cost depends on the ECU type).

Yes, a dealer can detect it. If they connect their diagnostic scanner and specifically check the ECU software version or calibration data against the factory baseline, they'll know something's been changed. Many dealers won't dig that deep, especially on a warranty claim unrelated to engine performance.

Your manufacturer warranty can technically be voided if a fault is proven to be caused by the tune. In practice, most tuned cars never encounter a warranty claim, and if they do, dealers often fix unrelated faults anyway.

We keep your original file. Before any major dealer service or warranty claim you're worried about, we can restore it in 30 minutes. Then restore your tune afterwards. This isn't dishonest — you own your car and its software.
