LML Emissions Equipped Tuning:

The 2011 through 2016 Duramax (or LML) is one of the best trucks GM has ever made.  However, the opportunity to make it even better is just instinctual for American diesel truck owners.

The most impactful improvement an LML owner can choose is aftermarket tuning.  As we talk with owners considering LML Tuning there are several questions that just about every truck owner will ask.  This article will provide the most common questions we are asked at DuramaxTuner.com along with corresponding medium-winded answers.

Finally you can switch power levels in an LML with EFILive Tuning by DuramaxTuner.com

 

The most commonly asked question about LML (2011 - 2016 Duramax) tuning is "When will switch on the fly power levels be available?"  Switch on the fly tuning has been available for the 2001 - 2010 Duramax trucks for years.  It offers many conveniences and is a favorite feature among enthusiast.  

Finally, DuramaxTuner.com has a working switch to adjust power levels while driving!  Much like the DSP5 switches for the previous model Duramax trucks, this new Switch on the fly LML Tuning offers a simple to install rotary switch along with the LML SPADE.

What is the the best tool a diesel enthusiast could ever ask for; a Mustang 4WD Chassis Dynamometer.  Why is that?  An 4WD Chassis Dyno gives you the ability to see exactly what your truck is capable of.  It also provides tuners the safe and controlled enviroment required to test calibrations and dial in your truck to best running condition.  Which in turn, gives you a truck that not only makes big power, drives as smooth as possible and gives you insight to when and how your truck performs at it's best.  

  • Find your PEAK Horse Power and Torque
  • Get the smoothest running truck possible
  • Gain insight into how and when your truck performs it's best

Many people have estimated horse power and torque numbers based on what someone else has told them.  A Chassis Dyno gives you the ability to know exactly how much power you have at the wheels.  No guessing or estimating involved since a dyno is a measurement tool at it's core.  

Beyond peak power, there is drive-ability to consider when you have a heavily modified truck.  Any tuner can make the peak power number, the difference between them is how the truck drives on the street.  Smoke output, shift points, throttle response and so much else can be dialed in when you are strapped to a dyno for testing.    

Diesel truck owners often want more RPM.  The logic here is that RPM equals power.  However, a chasis dyno gives you a clear picture of where and when your truck makes peak power.  When it comes to competing with your truck, this is crucial!  Diesel guys know all too well how close sled pulling or drag racing can be, so every possible edge really matters.

No need to delete emissions to make power!  

 

 

Many people looking to make more power with a 2011 and newer LML Duramax think an aftermarket exhaust is required to make power.  This is simply not true!  Countless people reach over 500 RWHP with just the LML SPADE and a lift pump.  

The most common myths about making power with an LML Duramax:

6 Things To Know Before Upgrading Your Duramax Turbo!

Stock Duramax Turbo Upgrades!

Duramax owners are generally proud of how their stock turbos perform.  They spool quickly, run hard and are capable of over 500 RWHP (once you tune it and make a few supporting modifications to handle the power).  However, after driving your truck around 520 RWHP for a while, the addiction will creep in and you may find yourself shopping for more power.  We all do it!  For some, it may not even be about more power, it may be about EGT control under load, or it may just be the factory turbo had an issue and needs to be replaced.  If you are anything like me, you will not want to replace it with the factory components if there is an upgraded, after market, charger available.

Drop-In Duramax Turbo Options

Drop-In Duramax Turbo Options

In the old days, there was no such thing as a "drop-in" turbo.  You pretty much had to buy a turbo that was designed for a different application and convert it to run on your Duramax.  Meaning the requirements for installation included several custom fabricated pieces to make it work.  

As technology in the diesel performance industry has advanced, our options for parts have expanded.  No longer do we have to use semi turbo's and roal coal to make power.  Now with the common rail injection system and variable vane turbo advancements there is a real need to find a turbo that makes more power than stock, while retaining all the benefits of a stock turbo. 

Benefits of a stock turbo:

  • Quick Spooling 
  • Clean installation
  • Reliable
  • Serviceable by any dealer or reputable shop
  • Requires no custom fabrication

However, they do lack peak power, and peak power matters!  When looking for which upgraded unit to replace the stock turbo, we recommend matching the replacement as close as possible to the desired power level to minimize compromising drive-ability.  Any extra capacity you buy in peak for performance will cost you low end response.  Example: Looking to make 650rwhp? Buy a turbo that can just barely squeak out 650rwhp, do not buy something that's good for 850rwhp because it will drive poorly a light load.

 My name is Danny Voss, I have been working with the tuning department at Duramax Tuner on our emissions equipped truck to get the most out of our LML (2011-2016)  Duramax

"The Clean Sweep" is Calibrated Power Solution's Emissions intact pull truck designed to kick butt on the pull track and drive home like nothing happened.  This truck is the true definition of a sleeper.  When I get on the throttle, the responsiveness is unbelieveable.  

Here are the TOP 3 Reasons why Duramax Tuner choose to do this project:

  • The EPA frowns on removing emissions equipment.
  • The future of our industry is going in the direction of CLEAN POWER.
  • To show the world we can make CLEAN, RELIABLE and LEGAL power.

INTRODUCTION:

Many customers have upgraded from their old pre-emissions Duramax to a new LML Duramax and found there are a few changes besides just the looks. 

The new LML made and astonishing 395 RWHP and 731 ft/lbs of torque on our dyno when tested stock. Which is impressive by itself but you will probably notice your old Duramax feels quicker. In fact we hear many stories of guys trying to merge into traffic or gun it to get in front of someone and the pedal does not seem to respond. This phenomena is often called the LML "Dead Pedal". The "Dead Pedal" is a delay the driver feels between pressing on the throttle pedal and the truck reacting as desired. 

 

But what causes the LML Dead Pedal? And more importantly, What is the fix for the LML Dead Pedal?

These are exactly the questions we hope to answer for you. Below you will see what we have put together on the topic.
