Follow these steps after you get your RTD4 in hand.
STEP 1 - Tune Form Submission
Once you receive your device, you will need to send us a copy of your stock tune through the TDN app and fill out the online Tune Form.
- You can find the tune form at this link: Tune Form
PLEASE FILL OUT THE TUNE FORM COMPLETELY AND ACCURATELY. Failure to accurately complete the tune form will cause delays in receiving your tune and/or could require additional charges to update your tune, after the fact, if you forget to include ALL modifications and information requested. Again, PLEASE FILL OUT THE TUNE FORM COMPLETELY AND ACCURATELY!
STEP 2 - Reading and Sending Your Stock File
Below, we have included several links to how-to pages that will walk you through reading and sending your stock file. The file will sync to our TDN account through the app. ALL HP Tuners based tunes require a read of the stock calibration to build your tune. We cannot build your tune until you submit your stock file, along with a completed tune form.
