Tow Smarter Without Giving Up Daily Comfort

If you’re using your 2016 Duramax for both work and play, the Light Tow Tune with EFI Live SPADE is the perfect way to unlock more usable power without sacrificing reliability. It’s designed specifically for towing loads under 8,000 pounds, giving you a noticeable bump in performance with smoother throttle response and cleaner acceleration. Whether you're hauling a small trailer, UTVs, or weekend toys, this tune helps your truck feel more responsive while staying easy to drive. With up to 55 extra rear-wheel horsepower and 99 ft-lbs of torque, it delivers the kind of power that lets you shift up and throttle back when you need to. Backing into a tight spot is easier too, thanks to revised pedal sensitivity that prevents lurching during low-speed trailer maneuvering. Best of all, it keeps your emissions equipment intact and is 49-state legal, so you can run it without the worry of failed inspections. It’s the kind of tune that brings your truck to life while keeping your day-to-day routine smooth and reliable.

Calibrated To Handle Light Loads With Confidence

This Light Tow Tune is a fully customized calibration built for the 2016 GM 2500HD and 3500HD equipped with the 6.6L Duramax LML. It includes over 100 tuning adjustments from stock, designed to enhance drivability, throttle control, and towing confidence without pushing the engine beyond its safe limits. The tune increases rear-wheel output by 55 horsepower and 99 ft-lbs of torque, but more importantly, it smooths out the powerband and ensures consistent performance when hauling lighter loads. Integrated SMART EGT control helps manage exhaust temperatures automatically, while built-in air-fuel ratio limits keep soot levels down under load. The factory turbo brake remains fully functional, and no emissions equipment needs to be removed. It comes bundled with EFI Live SPADE AutoCal v3 hardware, which allows for easy flashing, data logging, and diagnostics through a simple handheld interface. For trucks with custom tire sizes, modified intakes, or those used for work fleets, this tune offers refined control, enhanced safety, and peace of mind without overcomplicating the setup.
