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….

Horsepower Vs. Heat

Balancing Performance, Heat, and Reliability


Hold a cigarette lighter up to your thumb for a split second, people around you will look in amazement at how your skin magically tolerates it.  Hold a lighter up to your thumb for 5 seconds and get the ice water ready.  During those 5 seconds you're quickly using up your thumb's heat buffer.  This parallels what's happening inside your engine when pulling up a grade at GVW or passing on the highway.  Your engine has well engineered heat transfer pathways to dissipate heat from the 'front lines' the same way the blood in your veins moves heat away from your skin in the cigarette lighter experiment.  In the performance world we're concerned with 2 elements of these pathways, the first is the amount of heat the system can hold and the second is how quickly the system can move heat from the source. 


"Your engine has well engineered heat transfer pathways to dissipate heat . . ."

LML Power With Emissions: Facts & Myths!

[fa icon="calendar'] Jan 16, 2020 4:07:04 PM / by Justin Tyson posted in LML Performance

[fa icon="comment"] 0 Comments

The common myth that deleting the DPF and/or EGR to make power has gone on too long!

If you've been looking for ways to push your stock 2011 - 2016 LML with more horsepower, you have probably heard a lot of good information, but also a lot of misinformation. Most of the false things you'll hear are "the DPF will fail adding more power," or "More HP is going to clog the filter," and our favorite, "Deleted trucks get better MPGs!"  While you'll see these comments all over forums or on social media, there is simply no actual science or facts to back these claims.  So how much can your LML make? With tuning and a lift pump, you can expect over a truck with over 500 RWHP.

The History of the 5.9L Cummins

[fa icon="calendar'] Dec 16, 2019 10:08:04 AM / by Justin Tyson posted in Cummins, diesel performance

The 5.9L Cummins engine has been regarded as revolutionary and has a ton of fans that backed it in its heyday. It's history is even more impressive, we're going to talk about the engine's run from 1989-2007. 

1989 - 1993 

The Cummins engine had been successful in agriculture implements for a few years prior, so in 1989 Cummins and Chrysler introduced the 12 valve as an alternative the the V8 gas powered Dodge.  It was a hit immediately for those that wanted double the torque and a better option for fuel economy.  These diesel powered trucks were introduced stock with a 160 horsepower rating.  The truck was very simple.  Between 1989-1991 they offered a non-intercooled, turbocharged, and a three-speed automatic transmission, as well as a five-speed manual transmission option. Interestingly it had a rotary style mechanical injection pump.  These were the reason the truck was fuel efficient, but also why the truck lacked power. Another interesting point is how the original injectors were bigger than the next variation which arrived in '91.5.  The updated 12 valve now came with smaller injectors, a larger turbocharger, Cummins would introduce an intercooler to the truck, and the automatic transmission now came equipped with overdrive.
