What are some good upgrades if you are towing?

You bought your 2011 - 2016 Silverado HD with a Duramax to tow something with it.  It certainly is capable of performing well in completely stock trim.  Your truck has plenty of power to pull anything up to it's rated Gross Vehicle Weight (GVW), it stops well and the ride quality is superb. 

On the other hand, if you spend any length of time towing something you're bound to notice a few things that could be better. Furthermore, if you are towing for long distances, like a family vacation or for work, this LML Duramax engine has to be the most reliable vehicle you've ever owned.  

 

COMMON QUESTIONS LML OWNERS ASK:

  • What aftermarket products help with towing?
  • How can you improve MPG while towing?
  • Is the LML a reliable truck to tow something with?

5 Things You Probably Didn't Know About The 2011-2016 Duramax EGR

Some of you reading this are probably screaming at the computer already.  Mentioning EGR, or any emissions equipment tends to prompt that reaction.  Take a moment to read about how the EGR equipped on the 2011 - 2016 Duramax is NOT going to ruin your engine.  Afterwards, if you still want to send a letter about how terrible emissions equipment is, please address it to your local Congressman. 

Below you will find 5 things you probably didn't know about the EGR (exhaust gas re-circulation).  Including  how it is different than previous models, why it works well, and a few other note worthy facts.  

A few things you've heard people say about the EGR that are NOT true about the LML EGR system:

  • "They dump dirty exhaust back into your engine."
  • "The EGR will gum up and fail constantly"
  • "Deleting it will get you better fuel mileage."

STOP running your LML without a lift pump!

Do you need a lift pump on your LML?

You should strongly consider a lift pump for your LML (2011-2016 Duramax).  Although there are many benefits a lift pump provides, your LML needs them for 2 main reasons, RELIABILITY & PERFORMANCE. 

First, we should clear a few things up before diving into this topic.

  • Lift Pump:  A low pressure pump that draws from the fuel tank and pushes it to the high pressure fuel pump.  LML's do not have a lift pump from the factory.  
  • CP4.2:  High pressure fuel pump equipped on the LML.  Mounted in the engine bay, directly feeds high pressure to the common rail and draws fuel from the tank. Commonly called the Cp4.
  • LML:  Short hand for Chevy and GMC 6.6L, V-8, turbocharged, Duramax engines available in the 2011 - 2016 HD trucks. 
  • Brands: DuramaxTuner.com is an Authorized Dealer for FASS.  For purpose of this article we are not going to split hairs over brands.  We certainly suggest doing your research for what is going to meet your needs the best.

Is your LML TCM Tuned?

What is LML TCM Tuning?  Do you need it? How does it work?

 

If you own a 2011 - 2016 GMC or Chevy Duramax (LML) you probably know it is equipped with an Allison 1000 transmission.  You probably know this is one of the most respected transmissions to ever be matched with a diesel engine.   The Allison's smooth shifting and stellar reliability have earned it a special place in the diesel performance community.  

With all the benefits this transmission provides, it's not without it's own short comings.  Many LML owners have noticed there are times when it just doesn't shift they way want it to.  And when LML owners have questions, they know to call DuramaxTuner.com for help.  

Below you will find the 3 most commonly asked questions and answers on this topic.

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.
