Emissions Equipped, Twin Turbo, 2015 LML Duramax Build

Now that the LML platform has been around for almost 10 years(how?!), it's no shock seeing these models sporting a slew of modifications. This truck we are showcasing, it is built for a specific type of driver. That's the thing with your truck. You build it to how you drive your truck. That's exactly how this LML's driver approached it. Now let's take a look at exactly what this build entails.

Jamie Kerley, the VP of Duramxtuner, picked up this 2015 LML with 39,000 miles on and has been behind the wheel of the truck since. This GMC Sierra 2500 HD came completely stock with the emissions still intact (stock exhaust, functioning EGR & DEF). From the exterior, this looks like just any LML. Looks can be deceiving though….

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
