Turn Your Truck Into The Ultimate All Around Machine

If you want your Duramax to feel like it just leveled up in every category, the Switch-On-The-Fly Tune with EFI Live SPADE is the upgrade you've been looking for. This package gives you access to all five custom tunes so you can adjust power levels on the fly based on your load, driving style, or the day’s job. No more plugging in boxes or flashing the truck every time you want a change, just flip a switch and you're ready. Whether you're towing, daily driving, or just out having fun, each tune is designed to be safe for your truck and its emissions systems. You’ll feel the difference immediately, with sharper throttle response, better pulling power, and smooth acceleration across the board. The Street and Sport tunes will make the truck feel lighter and more alive, while the Heavy Tow and Light Tow tunes are built to get serious work done without beating up your drivetrain. It's not just about power, it’s about control, flexibility, and confidence behind the wheel. Once you’ve driven with this kind of tuning control, there’s no going back.

Five Custom Tunes Engineered For Total Drive Control

This tuning package delivers fully calibrated engine maps with over 100 changes from stock, tailored specifically for the 2013 Duramax 6.6L LML. It includes Sport, Street, Light Tow, Heavy Tow, and Optimized Stock tunes, each designed with precise air-fuel ratio limits and SMART EGT management to ensure reliable operation with factory emissions equipment. The Sport tune delivers up to 135 additional rear-wheel horsepower and 243 ft-lbs of torque, giving you aggressive performance when needed. Street and Light Tow tunes offer smooth drivability with power that’s ideal for daily use or towing under 8,000 lbs. Heavy Tow keeps your engine in its power band for long hauls and steep grades without pushing EGTs too high. Optimized Stock is perfect when handing the truck to someone else or troubleshooting. With the included EFI Live SPADE AutoCal v3, you’ll have simple plug-and-play access for tuning, diagnostics, and future updates. This is professional-grade tuning built to handle the demands of real-world driving.
