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. Additionally, these tuners can make your GM 6.6L Duramax LML feel like a whole new rig by correcting your GM 2500/3500 for an increase in tire size, change in gear ratio, or a new exhaust system that requires tuning. 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. Keep tabs on your engine parameters and experience a more powerful ride with any of the high-quality tuners we offer for the GM 6.6L Duramax LML equipped trucks, right here at Alligator Performance!
