It’s built for real-world drivers who want more control, cleaner power, and better drive-ability. The Sport Tune delivers head-snapping acceleration, while the Street and Light Tow tunes give you a smoother feel for everyday use.

It’s the kind of upgrade that makes every part of your truck feel sharper, stronger, and more fun to drive.

Every Tune Is Calibrated With Precision And Purpose

Behind the scenes, this FIVE Tune Pack is the result of more than 100+ detailed calibration changes crafted specifically for your 6.6L Duramax LML. Each tune is emissions-intact and 50 state legal, delivering real performance gains without tampering with your truck’s emissions equipment. The package includes tunes that range from mild to wild: Optimized Stock for troubleshooting or conservative driving, Heavy and Light Tow for safe pulling up to GVW, and performance options like Street and Sport that push your truck to its full potential. Air-Fuel Ratio limits and SMART EGT Control are built into every calibration to help reduce soot and control exhaust temps. It retains factory turbo braking and features revised pedal sensitivity for better low-speed trailer maneuvering. When paired with TCM tuning, it also enhances transmission performance for smoother shifts and stronger torque management. All this tuning power is delivered through the EZ Lynk platform, making updates and diagnostics simple and accessible right from your smartphone.
