Motor Ops EFILive AutoCal

Motor Ops has spent countless man-hours fine tuning the calibrations on their AutoCal device so that your 2007.5-2010 6.6L GM Duramax LMM performs to its highest potential while still maintaining excellent driveability, heat, and smoke control. This product comes pre-loaded with five tunes and all of the hardware and cables required for installation.

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.

Power Levels
