As the winter months rolls around us diesel owners get an unexpected bit of stress added to our plate. Diesel fuel gelling is a very common issue most diesel owners who live in areas where the temperature drops below 32 degrees will face at least once in their lives. Not only is this issue frustrating and stressful when it occurs, the mere trauma from past experiences can lead to constant stress during these cold times. No one wants to get out of work in the pitch black freezing cold only to find that their truck won't start at all. But what should you do in the event that your truck won't start or stay running? Luckily we have a step by step guide on how to properly fix this issue once it has occurred. 

 

 

As a preface, this issue is caused when the paraffin wax used in diesel fuels (for lubricity and proper viscosity) start to solidify.  While gelling can take on varying levels of severity from cloudy fuel all the way to a squishy solid mass. Diesel fuel gelling is never a thing you want to expeirince. At its most mild levels it can cause poorer fuel economy, less power, and be pretty hard on your fuel system. At its worst I can clog fuel lines, filters, pumps and even injectors while potentially causing irreversible damage to your fuel system.  If you live in a cold climate take precautions by adding anti-gelling agent into your fuel before severely cold temperatures start setting in to avoid all of these issues.

Stock Duramax Turbo Specs and Information

Over the years, GM has changed a lot regarding the turbos they use on Duramax engines. Not only have they changed manufacturers a handful of times but each RPO has its own unique measurements for key components. This can make it a headache when trying to track down exactly what the measurements of your stock turbo are. Luckily we've compiled this list of stock Duramax turbo specifications along with other helpful information so you can get a good idea of what you're already working with before you dive into the sea of turbo upgrades these trucks have to choose from. However, while some turbos may have the same peak power output, the size and shape of specific components can affect things such as exhaust gas temperature, drive pressure, and turbo efficiency range.

GM 3.0L Duramax Custom Tuning

The 3.0L Duramax is a wildly capable inline 6-cylinder diesel engine designed for full-size half-ton pickup trucks and SUVs. Due to its amazing power-to-weight ratio and towing performance, GM has chosen to offer this engine in everything from Chevy Silverado 1500 to the Chevy Suburban and even the Cadillac Escalade. Clearly, GM is confident in its new design. 

The new 3.0L Duramax shares very little in common with its predecessor the 4-cylinder 2.8L Duramax. It's been completely redesigned from the ground up and features many improvements such as a forged crankshaft, forged steel connecting rods, and a much stronger block design. The result is an engine that can produce 277 hp and 460 ft-lbs. of torque. Which is comparable torque to that of the more expensive 6.2L gas engine that is offered in most of the same vehicles that the 3.0L is offered in.

What's an RPO? Crucial Duramax Information!

What's an RPO? Crucial Duramax Information!

 

This article will help you understand what an RPO is, how to find yours and when it will be needed.  An RPO or Regular Production Option is a GM-specific code, made up of 3 characters, that helps the manufacturer specify what configuration of options has been or needs to be applied to a vehicle. This can include anything from paint color to powertrain options. For Chevy/GMC Duramax trucks each type of engine can be signified by a different RPO code.

Don't Delete Your 2017-2020 L5P Duramax DPF!!!

Do you need to delete your L5P DPF?

We've all heard from forums and numerous outlets that deleting your DPF system is the way to go these days. What we never see backing these claims is data and tests. There is plenty of personal stories around a failed sensor or even the occasional DPF failure. However, once data starts fueling the debate on whether to delete or keep your emissions intact you may change your mind of what to do.

The Duramax engine has a history that runs deep.  It has the following still to this day and continues to up expectations in terms of power and everything else. While it's history stretches back to 1982, we are going discuss the more modern years. The 6.6L was introduced in 2001 and replaced the 6.5L and the company hasn't looked back since.

1,045 RWHP Duramax Powered Suburban

 

 

"There are few things in life more badass than a 1050rwhp Suburban.  I can't say enough good things about the team that made it happen.  Between my shop guys burning the midnight oil, Bob tuning it, and our awesome vendors Exergy and WcFab.  This thing is incredible." -Nick Priegnitz

This 2004 Suburban was originally converted to run a 2006, LBZ Duramax at Duraburb in Apopka, FL.  Back then, the truck had just a built trans, small drop-in turbo and stock CP3.  Now, it's a tire shredding, family hauling, quarter-mile blasting MONSTER!

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.

#DTCLEANSWEEP - Parts List of how to make power!

 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.

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!)
