How it Works

Because this tuning is custom made for your specific needs and modifications, the Gorilla EFILive AutoCal will not come pre-loaded. Each unit ships with easy-to-follow instructions that include a login, password and unique order number to use on the Gorilla website. You will be directed to an online portal where you will be asked for information about your truck. This information includes VIN number, modifications and more. Once these fields are filled out and the form is submitted, the experts at Gorilla will build tuning specifically for your truck.

Within 48 hours (business days) you will receive the tunes via email. From there you can load the tunes onto the AutoCal and then into your truck. Each tuner ships with unique information. For this reason, the above process cannot be completed until you physically have the Gorilla AutoCal.

2011-2016 GM 6.6L Duramax tuning comes as 5 separate files. To change power levels you must re-program your vehicle with the AutoCal.

Power Levels

  • No Power: +20HP

WARNING! These products are capable of disabling emissions equipment. If using DPF/EGR removed tuning, these high performance products are intended SOLELY for offroad use or closed-course racing use.
