Diesel engines are renowned for their power and efficiency, but they also come with complex emission systems designed to reduce harmful pollutants. Two critical components of these systems are the Exhaust Gas Recirculation (EGR) valve and the Diesel Particulate Filter (DPF). When these components fail, it can lead to decreased performance, increased emissions, and costly repairs. Understanding the common causes of EGR and DPF failure can help you maintain your diesel engine in top condition. Here are the top three causes of failure for each component:

2011-2016 Ford Diesel Dead Pedal

Many customers have upgraded from their old pre-emissions Powerstroke to a new Ford 6.7L and found there are a few changes besides just the looks. 

The2011-2014 F250 and other diesel models made and astonishing 400 RWHP and 800 ft/lbs while the 2015/2016 Powerstroke makes 440 RWHP and 860 ft/lbs of torque. Which is impressive by itself but you will probably notice your old Ford diesel 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 Ford 6.7L "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 Ford Diesel Dead Pedal?  And more importantly, What is the fix for it?

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

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.

LML Stealth 64 VVT by DuramaxTuner.com

 

The Stealth 64 turbo lineup has provided Duramax and Cummins owners the perfect drop-in, upgraded turbo option to net 80-120 extra horsepower.  It spools like stock, appears stock, and still makes good power.  The Stealth 64 lineup has already supported the 04.5-07 Cummins and the 01-10 Duramax.  Significant changes in design of the factory turbo slowed our entrance to support the 2011 - 2016 Duramax trucks.  Until now! 

 

This turbo has an upgraded compressor and turbine.  It's a direct bolt in for the factory charger on the LML (Custom tuning Highly Recccomended!)

Shift Up, Throttle Back Review

Shift Up, Throttle Back, What is it?

Many farmers run their large 4WD tractors while performing tillage work. Generally they find a gear that lets them achieve a desired ground speed and run at WOT. This practice will get the job done, no question. However, operators may see the Gallons Per Hour go up while this work is performed. This is a result of the tractor running more RPM than neccessary for the drawbar requirement. The amount of power needed for most drabar activities is probably not the peak power output of the tractor. This excessive RPM operation is the root cause of wasted fuel.  Good news though: Iowa State University, University Extension studied the "Shift Up, Throttle Back" strategy and have given suggestions on how to save fuel.  In fact, during testing some tractors measured up to a 20% reduction in fuel useage.

How does REGEN work in an LML Duramax?

[fa icon="calendar'] Jul 6, 2016 10:30:43 AM / by Paul Wilson posted in Insider, DuramaxTuner.com, Duramax, Emissions, EGR Delete, 2013, 2014, 2016, Add blue, DPF Intact, EGR ON, DPF ON, 2011, 2015, New Diesel, LML, Diesel Tuning, More Power for my LML?, Urea, 2012, Delete, DPF Delete, Urea Delete, LML Tuning, Emissions Intact, EGR

REGEN is the burning of soot built up in a DPF. 

 The Emissions Equipment for diesel trucks has changed quite a bit through out the years. In 2004.5 all heavy duty diesel pickups had to install EGR's which is the exhaust gas recirculation system. Basically it turns exhaust into inert gas and directs the gas back into the combustion process. Then in 2007.5 the EPA required pickups to use a DPF. The DPF, or Diesel Particulate Filter, is a filter that catches soot, or unburnt fuel from the exhaust. Once the soot builds up, the exhaust heats up to burn the soot off. Starting in 2011 Diesel Exhaust Fluid is used to treat NOx emissions, in addition to the EGR and DPF treating the carbon emissions. 

The DPF is a crucile part of treating diesel emissions and each OEM utilizes and operates their DPF a little differently. Below, the DPF in the 2011-2016 LML Duramax is explained.
