  3. 8 tuning credits.
  4. A year-specific CAN plug kit.
  5. Either a DPF-delete pipe or a complete delete-exhaust system.
  6. Disconnection or removal of the EGR system.
  7. A comprehensive tune package.

*Ensure that your ECM is free from any emissions-related diagnostic trouble codes (DTCs).*

We have all of these items bundled HERE


If you bought a new unlocked ECM, refer to this guide.

If you purchased the E41 unlock tool to unlock your factory ECM, refer to this guide.

After receiving the necessary parts, install the latest version of VCM Suite BETA. This software is essential for generating the read file and info log required for creating your tune. The HP Tuners TDN phone app is not necessary; only the VCM Windows software is needed.

Once you receive your tune file(s), make sure to load them before continuing with any mechanical work.
