A Quick Tip on the TDN App: After Read Vehicle is complete, the App will say “Files have been sent to your tuner.” This message only means the files are accessible to us—a Tune Request is still required.
Linking us as your tuner gives us permission to view/send/receive files.
Submitting Tune Requests notifies us that your files are ready for review.
Including your TDN Email where requested ensures we can find your account.
The easiest way to navigate the device setup and tuning process is to follow along with our Tuning Guide.
You will use Tuning Central to submit your preferences and requests related to tuning, and a Tune Request is required each time you sync/upload a file for review in the TDN App.
You can make additional changes/requests throughout the process and post-finalization by submitting Tune Requests. All Requests go directly to our tuner. These requests serve as tickets in our tuning queue and are answered in the order they were received.
