About TDN

Tune Delivery Network (TDN) is a suite of applications that allows tuner files to be exchanged with the customer. The suite includes:

A mobile app that allows customers to retrieve scan files from their vehicles, send them to you, and then apply your tuned files when they are completed.
A website (portal) that is used by tuners to accept new customers, receive their scan files, keep the received files organized by customer and vehicle, and send completed files back to the customer.

This guide is for tuners using the TDN portal.

Information on using the TDN mobile app is also included in order to help tuners to support their customers who use it.
