520 RWHP TUNE ONLY LML DURAMAX:
The 2011 - 2016 LML Duramax came rated at 395 horsepower and 765 ft/lbs of torque. That seemed like an amazing amount of power when this model was first released but these days it is dwarfed by the available power of brand new trucks.
Furthermore, that whopping 395 HP is a peak power rating, meaning that you probably won't produce that much power during normal operations. In fact, many owners complain that the power delivery of the stock tune is too soft. This is why custom tuning is so important for the LML Duramax.
Here are some of the things tuning your LML can help with:
- Increased Peak Horse Power
- Improved Shift Quality
- LML Dead Pedal Resolution
