Sport Tune Only for EFI Live Spade - LML (2012)

This Sport Tune provides significant power gains for the 2012 GM Silverado or Sierra 2500HD/3500HD with the 6.6L Duramax LML engine. It offers an increase of up to 135 horsepower and 243 lb-ft of torque, resulting in a total of 532 HP and 1008 lb-ft. The tune focuses on improving throttle response and acceleration, eliminating the "dead pedal" sensation. It is 49-state legal, emissions compliant, and keeps all emissions equipment intact. The tune features over 100 custom calibration changes to fuel delivery, torque management, and throttle mapping. It includes an EFI Live AutoCal V3 (SPADE device) for OBD flashing and data logging. While it can be used for towing, proper gauges (including EGT monitoring) are strongly recommended due to the increased output. Transmission tuning and supporting fuel system upgrades are also encouraged for optimal performance and for experienced tuned truck drivers. EFI Live license is required per vehicle.
