Make Your Daily Drive Feel Like Something Special

If your 2016 Duramax feels a little too tame for your liking, the Street Tune is the upgrade that gives it a more exciting edge without sacrificing daily drivability. With gains of up to +110 rear-wheel horsepower and +198 ft-lbs of torque, this tune delivers immediate throttle response and faster acceleration that makes the truck feel noticeably lighter. It’s perfect for drivers who want more power on the highway or just enjoy the way a tuned diesel feels underfoot. You’ll still keep full emissions compliance and factory turbo brake functionality, making this a clean, reliable solution for street-driven trucks. Whether you're commuting to work or hitting the highway for a weekend trip, the smoother power curve and improved pedal response make every drive more enjoyable. It's not designed for towing heavy, but for everything else, it gives your Duramax that extra kick you've been missing. And with the EFI Live SPADE tuner included, it’s all plug-and-play from the comfort of your own driveway.

A High Performance Calibration Designed For Street Ready Power

This Street Tune is built for the 2016 Silverado and Sierra HD equipped with the 6.6L LML Duramax and delivers one of the highest horsepower gains available while maintaining emissions compliance. The calibration is developed using over 100 changes from the factory file, including adjustments to injection timing, torque limiting, throttle sensitivity, and boost control. The result is a sharper, more responsive truck with stronger midrange power and quicker acceleration, all while keeping your emissions systems intact. It produces less soot than typical box tuners thanks to carefully managed air-fuel ratios and does not require any sensor splicing or mechanical modifications. The tune is 49-state legal and comes paired with the EFI Live SPADE AutoCal V3, which allows you to flash your truck through the OBD port and log diagnostic data as needed. While it's not recommended for heavy towing, it handles occasional light towing just fine. For trucks with driveline or tire upgrades, TCM tuning is also suggested to ensure optimal shift performance and clutch protection.
