Stealth Tune Process - PCM Unlock

Once you place your order, you will receive an email with a video explanation of the process, a form link, and the invite code. 

The form link is to get specifics on the type of vehicle you drive, your VIN number, any and all modifications you currently have, and more. All of these questions ensure you get the best results for your vehicle. 

The RTD is a remote tuning device supported by the HP Tuners platform. This allows the TDN app (tuning network) and your vehicle to communicate.

The next steps will vary depending on if we are unlocking your PCM or if you chose to order a NEW unlocked PCM. Scroll to the appropriate section.

Unlocking Your PCM:

Attached to the first email will be a shipping label. Please use this to ship us your PCM. Once we receive it, we will unlock it and ship it back to you along with your RTD. After you receive your RTD and unlocked PCM you are ready to fill out the form. 

  • Download the TDN app - iPhone or Android 
  • Sign up for an account
  • You will then be prompted to plug the RTD into your OBDII port
  • The TDN app will walk you through the process
  • During setup, the TDN will ask for a Tuner ID (invite code) - this will be provided to you in the email after purchase
  • Once your stock PCM file is downloaded, uploaded and synched to our backend, then we will get started!
