DIGITAL TUNE DELIVERY The tune itself is delivered by email. No physical tune is shipped, and no tracking number is expected. Your calibration file and applicable flashing instructions are sent to the email address used at checkout. Choose one stage before checkout; this purchase includes one file for that stage. After ordering, email your order number and setup details as described below so we can confirm the right file. A full ECU read is not required unless Poverty Built requests one after reviewing the order. Flashing software, licenses, cables, and interfaces are separate unless this listing or your order specifically says they are included. If your order also includes a cable or other physical hardware, that item ships separately. A shipping label means the package is being prepared; it is not in transit until the carrier receives it.
