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."

Whether you are in the field yet or not, you already know what machines in your operation could use more power.  Maybe your 4WD unit that does tillage work or if you have been thinking about running a larger implement but not sure if you got enough ponies to drag it.  Either way you need power.  

To be clear, this is not for those trying make a competition tractor!  This is for those that use their tractor to make a living.  This is for the farmer that needs more power but certainly can't afford to have broken equipment and trading in at the dealership is just too expensive right now.  

We plan to put the entire build into a FREE E-Book which will be available by the end of June, 2017.  If you would like a copy just click the button below and fill out the corresponding form.  

What is the best tuning for a 2016 Cummins?

This is a common question these days.  Many Cummins owners like you understand the importance of high quality, custom tuning.  However, figuring out which custom tuning platform is best for you can be complicated.  

EFILive has a great reputation and is a favorite among diesel tuners.  MM3 hardware and UDC Pro Tuning is derived from Smarty, a company that also has a stellar reputation among Cummins owners.

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. 

What do you need to make 600HP in your LBZ?

600 RWHP (Rear Wheel Horsepower) with your LBZ makes one of the most fun trucks to drive!  They sound great, look amazing and feel like a rocket ship if you do it right.  

(Chuck Dilley's LBZ  was actually a lot more than 600HP when this picture was taken, but it's a great picture)

There are many recipes out there to make this power.  Each with it's own advantages and shortcomings.  Below you will find our recommendation assuming you meet this criteria:

- Drive-ability is crucial! It's not just about a number on the dyno, you want to be able to daily drive this build when you are done.

- You are NOT trying to sled pull in a 2.6 or larger class.  

- The truck must maintain its reliability.  You don't want to constantly worry about blowing a motor. Or maybe you tow with it and want to (or have to) still let the wife drive it once and a while. 

The 2.8L Duramax in the Colorado and Canyon is a great engine!  Overall they are great trucks! 

They get even better once you fix the biggest complaint about them: the Dead Pedal.

Let's say you're driving your new Canyon 2.8L fresh from the factory, no aftermarket tuning. You want to pass, so you step on the throttle, and wait, and wait.

The turbo charger has to lead the charge. There's a transient response rate. The delay in that transient response is the dead pedal.

The dead pedal delivers less power than the driver anticipates. The untuned 2.8L feels like there's a tennis ball stuck behind the pedal.

Last year we ran our 2012 Duramax with a few aftermarket goodies and the stock emissions equipment.  Not only did the truck compete the entire season, it won several events!  Taking home 5 first place spots and placed in the top 3 more often than not.  

With 617 RWHP on tap DT Clean Sweep almost made it look easy.  

The 2017 sled pull season is approaching and we wanted to a way to give back to you, our fans!  So we are offering a FREE Poster featuring #DTCleanSweep shipped to you!

Our truck  started life as a cab and chassis, 2 door Cummins powered Ram.  

We decided to stuff a 640 cubic inch Cummins in it, throw triple s500 turbos on it, twin 14mm stroker pumps and giant injectors into it.   And although the project is already put together, you can follow along to learn what it took for this monster to come together.

This is an excert from the thread we have going at CumminsForum.com titled Big Block, 8.9L Build

We are going to work up a FREE UCC Truck Build E-Book.  We are projecting to have them done by the end of June, 2017.  If you would like to request a copy just click the button below and fill out the corresponding form.
