Just let us know your upgrades and preferences, and we will have the tunes written to accommodate any modifications your truck may have.

IMPORTANT: This process requires an Unlocked HP Tuners ECM via HP Tuners send-in service and the LM2 Duramax CAN BUS Plug Kit.

We do not support lope tunes or smoke tunes.
