GDP Tuning EFILive Autocal | 2007-2009 6.7L Cummins | R0709CGP

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.
