The Most Power You Can Run And Stay 50 State Legal

If you own a 2015 Silverado or Sierra 2500HD or 3500HD LML and want serious power without pulling off emissions equipment, this Sport Tune is where things get exciting. DuramaxTuner designed this calibration to deliver the strongest gains possible while remaining 50 state legal, so you are not forced to choose between performance and compliance. With gains up to plus 135 horsepower and 243 lb ft of torque, the truck feels lighter, quicker, and far more responsive the moment you touch the throttle. There is no dead pedal sensation, just clean and immediate acceleration that makes highway merges and spirited driving a lot more fun. Additionally, the firmer shifting helps put power to the ground in a way that feels controlled rather than chaotic. This is the tune for the driver who wants the adrenaline rush but still appreciates a professionally engineered calibration. If you plan to build the truck further down the road, this Sport Tune gives you a strong foundation to grow into.

Advanced Emissions Compliant Calibration With Included AutoCal V3

This package includes the EFI Live AutoCal V3, also known as the SPADE device, giving you the hardware needed to flash and manage your custom Sport Tune. The calibration itself features more than 100 changes from stock, carefully adjusting fuel delivery, torque management, and throttle mapping to safely increase output. Rated at a total of 532 horsepower and 1008 lb ft of torque, it represents the highest performance level available while remaining 50 state legal under E.O. D-845. Furthermore, the tune retains full factory emissions functionality and does not require cutting wires or altering sensors. The AutoCal V3 also functions as a scan tool, allowing you to log engine data for diagnostics and performance monitoring. For optimal drivability and durability, transmission tuning is strongly recommended, especially on trucks with larger tires or additional power modifications. When properly supported with upgrades such as a lift pump and fuel system improvements, this Sport Tune delivers controlled, emissions compliant performance that transforms how your 2015 LML drives.
