We ask for your VIN up front so the calibration is built for your exact car — not a generic file.
Before you order
Not sure this is the right file for your car? Ask first — we would rather talk you out of the wrong product than refund it.
Your factory file is archived
Going back to stock is always one flash away.
Built for your VIN
That is why we ask for it at checkout — the calibration is written for your exact engine and software version, not a generic map.
Support after the sale
