Sport Tune Only for EFI Live Spade - LML (2016)

If you want your 2016 Duramax to hit harder and feel completely unleashed, the Sport Tune for EFI Live Spade delivers exactly that experience. This tune is built for drivers who crave maximum acceleration and want their truck to feel aggressive the moment they touch the throttle. With up to 135 horsepower and 243 ft-lbs of torque added, the truck pulls with authority and never feels lazy or muted. Throttle response is immediate, eliminating the dead pedal feeling that holds these trucks back from the factory. Every gear change feels firm and intentional, making the truck feel lighter and far more eager to move. This is the tune for those moments when you want the biggest adrenaline rush that is still emissions intact and legally calibrated. If you miss the raw excitement of a high horsepower diesel, this tune brings it back in a big way. The Sport Tune is a custom calibration developed specifically for the 2016 GM Silverado and Sierra 2500HD and 3500HD with the 6.6L Duramax LML. It features over 100 detailed calibration changes designed to deliver peak horsepower and torque while maintaining emissions equipment and 49 state legality. Fuel delivery, throttle mapping, and torque management are refined to produce 532 total horsepower and 1008 ft-lbs of torque at the engine. This tune is intended for performance-focused driving and should not be used for frequent heavy towing without proper gauges and monitoring. It is flashed through the EFI Live Spade AutoCal V3, allowing clean installation through the OBD-II port with no wiring or sensor modifications. Transmission tuning is strongly recommended to handle the added power and improve clutch holding capacity under load. When paired with the proper supporting modifications, this tune offers a controlled and repeatable way to push your Duramax to its legal performance limit.
