The Sport and Street tunes wake the truck up with strong throttle response and real seat of the pants power that makes it fun again. When it is time to hook up a trailer, the Light Tow and Heavy Tow tunes deliver controlled power that feels confident and predictable. Everything stays emissions intact and fully 50 state legal, so you can enjoy the upgrade without added stress. The Optimized Stock tune is perfect for lending the truck out or keeping things calm when needed. It is the kind of setup that feels thought out, not overdone, and makes you enjoy driving your Duramax every day.

Purpose Built Calibrations Designed For Real World Driving

Each tune in this pack is built from the ground up with over 100 calibration changes, not generic adjustments. Power delivery, throttle mapping, and torque management are refined to work with factory systems instead of fighting them. SMART EGT control and air fuel ratio limits help manage heat and soot, especially when towing or driving under load. Turbo brake functionality remains fully intact across all applicable tunes for better control on grades. The Light Tow and Heavy Tow calibrations are designed around real weight limits, keeping power usable and predictable. Sport and Street tunes focus on smooth power curves instead of harsh spikes that hurt reliability. Everything is flashed through the EFI Live AutoCal v3, making updates and adjustments straightforward while keeping your truck operating within safe and proven limits.
