  • Full Support Package
  • Limited Support Package
  • SOTF Switch

The Proven Diesel Full Support Package offers unlimited flashes and basic tune revisions on ALL TUNES. You’ll receive automatic tune updates so that you can take advantage of the progress that we make and enjoy the timelessness of the EZ LYNK AutoAgent. Every support package includes unlimited datalogging and chat features so that you can reach a Proven Diesel tuner from anywhere, at any time.

The Proven Diesel Limited Support Package. Our limited support packs give you access to all Proven Diesel tuning compatible with your vehicle for 4 weeks. This is convenient if you’re seeking a single tune to install on your vehicle. Once the 4 week expires the tune that is currently in your truck will remain. Upgrading to Full support will give you access to all tuning and software updates indefinitely.

Call Proven Diesel prior to your purchase to get help making a tune selection.

The SOTF Switch is needed to correctly run SOTF tunes. Without the switch installed, your tune will default to the lowest power level. Installing the switch will allow you to adjust power levels and maximize your vehicle’s performance instantly.

No re-flash is required!
