Flow VIN Tune

Frequently asked questions

Which vehicles do you support?

Alfa Romeo only, for now. We focus on a tight whitelist of Alfa Romeo ECU families so we can review every file properly.

Which calibrations do you offer?

Stage 1 and Stage 1+ only. We do not offer Stage 2, and we do not touch emissions systems (no DPF/EGR/SCR or catalyst changes) or any defeat device.

Is the tune automatic?

No. Our AI proposes a candidate calibration, but an expert human tuner reviews and approves every single file before you can download it. There is no auto-delivery.

What exactly do I receive?

A tuner-approved calibration file with delivery notes and checksum metadata, delivered over a time-limited secure link. Every file version carries an immutable SHA-256 hash.

What do you do with my data and VIN?

Your files are stored immutably and access is logged. We never store your raw VIN — only a one-way hash. You can request revert-to-stock at any time.

Will this affect my warranty or road-legal status?

It may. Tuning can affect your vehicle warranty and road-legal status, and you are responsible for compliance in your jurisdiction. We make no claim of warranty compatibility.

Do you guarantee a power figure?

No. Results depend on your specific vehicle, fuel, and hardware. Stage 1+ includes a written per-ECU contract describing the declared setup and expected gains.

Can I get a refund?

Contact support before a tuner has approved your file. Once an approved file has been delivered, refunds are handled case by case.
