The factory PCM programming for your 2011-2016 GM 2500/3500 does it's job for stock equipped trucks; however, there's tons of more power and performance hiding under the hood of your 6.6L Duramax LML, especially after modifying your truck. These premium performance tuners help unlock more horsepower, torque, and throttle response by making adjustments within your truck's ECM.

Many of these devices even work overtime as effective vehicle monitors so you can better keep tabs on your truck's critical running information to spot problems before they become disasters.
