Five Proven Tunes To Match Every Drive

If you want your 2013 Duramax to handle anything you throw at it, this 50-State Legal Five Tune Pack with EFI Live SPADE gives you the flexibility to dial in the perfect power level for any situation. Whether you're towing a heavy load, cruising through city traffic, or just letting it rip on an open road, each tune is purpose-built to deliver the best balance of power, efficiency, and control. With gains of up to 135 rear-wheel horsepower and 243 ft-lbs of torque, the Sport Tune turns your truck into a powerhouse when you want max performance. On the other hand, the Street, Light Tow, and Heavy Tow tunes give you smooth power curves and advanced control for daily driving or working under load. Even the Optimized Stock tune has its place, offering a reliable setup when you're troubleshooting or letting someone else borrow the truck. Every tune is emissions intact and CARB approved, so there’s no need to worry about inspections or legality. It's all backed by EFI Live's AutoCal hardware and the expert support of DuramaxTuner.com, giving you complete control with confidence.

Custom Calibrated Power With Clean Emissions Compliance

This 50-State Legal Five Tune Pack is a complete tuning solution built for the 2013 Silverado and Sierra HD equipped with the 6.6L Duramax LML. Each of the five tunes is crafted with over 100 changes from stock, giving you more precise throttle control, cleaner combustion, and better overall performance across a wide range of driving scenarios. The included EFI Live SPADE AutoCal v3 hardware makes it easy to flash tunes, log data, and troubleshoot with a user-friendly interface. With tunes designed for sport, street use, light and heavy towing, and optimized stock conditions, you're able to tailor your truck’s behavior based on your workload or driving goals. SMART EGT control helps manage exhaust temperatures, while built-in air-fuel ratio limits reduce soot without impacting reliability. Turbo braking is retained on all tunes, and the calibration remains fully emissions compliant under CARB EO# D-845. For trucks with minor mods or those staying stock, this tune pack delivers maximum versatility and performance without crossing legal or mechanical limits.
