These are the first 4 upgrades you should make to your 2003-2007, 5.9L Cummins.

If you're just getting into the diesel game with a third-generation Cummins 5.9L you're on the right track. While people say the 12v motors are great for being able to handle lots of power and having lots of upgrades. The 24v is also a very solid choice for both of those same reasons. With more hp from stock than the 12v motors and some beefy internals, like forged rods that can handle over 800hp. There is lots of potential to be had. 

It's a great truck from the factory, but if you're anything like the rest of us you're not interested in keeping it stock. Especially with the number of bolt-on upgrades available for the 5.9L. Why not make a great truck even better? Today we will show you the first 4 mods you should do to your 5.9L Cummins turbo diesel. 

Your 6.7L Cummins NEEDS an upgrade!

The  Ram 2500 and 3500 HD pickups with a Cummins 6.7L are made for towing.  You know that. We know that. Everyone knows that. However, a lot of guys are clueless when it comes to which upgrades are worth it and which ones are a total waste of money. 

WILL THESE BE THE RIGHT UPGRADES FOR YOU? 

This list is based on an assumed set of circumstances. You have a 2013, 2014, 2015, 2016, 2017, or 2018 model year Ram 2500 or 3500 equipped with the Cummins 6.7L diesel engine. Your truck is completely stock (no modifications) or very near stock. You have not already deleted the emissions equipment or upgraded major performance components such as the turbocharger or high-pressure fuel system. 

Drivers that use their truck as a truck will find this list especially helpful. Towing, commuting, and getting it up and moving when you need it to have to be balanced with reliability and efficiency.  On the other hand, if you're looking to build a competition truck for sled pulling, drag racing or dyno competitions, our recommendations may drastically change. 

• 2013-2018, Cummins 6.7L 
• Stock or Near Stock Truck
• Drive your truck regularly
• 68RFE Automatic Transmission
• Use truck for towing
• NOT interested in building a race or competition truck
• Cares about efficiency and reliability
• Want superior drive-ability

One of the most misconstrued topics in the diesel world is how emissions equipment impacts your truck.  Many people believe that deleting your Cummins DPF will enhance your truck’s performance and help solve DPF/EGR failures.  Well, the data around these systems has been building up for quite some time.  With enhancements of the DPF and EGR engineering, these systems aren’t like they were when they first hit the market in 2007.5.  When Cummins moved from the 5.9L engine to the 6.7L the DPF was brand new and as with many first-generation parts, failed often. 

Now, if you think that simply deleting your DPF is going to gain you 100 HP and 5 MPG, you're going to be surprised by what we have found with real-world data.  Not to mention, the current state of EPA involvement within the diesel performance community should be on your radar if you are looking for deletes. While social media, keyboard warriors may shout like they all the answers, you will want to know.

THE TOP 5 REASONS NOT TO DELETE YOUR CUMMINS DPF!

As technology and research continue to accelerate the quality of the EGR system, it's something that due to it's poor quality at early inception has faced continual backlash.


EGRs on the cummins have been around now for over 10 years. While the infancy stage of the EGR came with many hiccups and issues amongst all the Duramax, Cummins, and Power Stroke diesel trucks. It’s understandable to see why so many dislike these emissions systems, but this isn’t the mid-2000s anymore. These systems have progressed over the years and we wanted to see exactly just how well.

Calibrated Power Solutions, home of Duramaxtuner.com, have released their industry leading emissions equipped tuning on EZ Lynk for all 2013 - 2019 Cummins diesel trucks.

The 2013 to 2019 Cummins 6.7L diesel truck is consistently one of the top selling of the big three diesel trucks. You can see why, this truck has power straight outage factory, it’s got the towing capacity, and payload.  Take those aspects and combine them with the updated interior, ride quality, and improved emissions systems, well, these trucks are truly remarkable.

This "How To" article will walk you through installing the EFILive CSP Switch on your 2006 - 2009 Cummins powered Ram 2500 or 3500 pickup truck. 

CSP Switching has been around for quite a few years.  The programming provided via EFILive allows your engine computer (PCM) store 5 separate tune files and the CSP switch can rotate through them.  

NEED CUMMINS TUNING

A simple tune can dramatically change the dynamic of your truck in many ways!

The Cummins has gone through so many adjustments to help benefit the truck with each new generation introduced.  We've seen convenience and comfort get pushed along too, it's all apart of getting the owner to love what they drive.  The thing truck owners love the most is how much more horsepower and torque get updated in addition to body styles and interior.  In the late 80's the 12 valve was pushing a mere 160 RWHP out of the factory.  Look at where we are at now, the CME (2013-2018) is now putting down between 350-370 RWHP depending on transmission.  That's a huge difference in the matter of a few decades.  This is amazing to see, but it doesn't mean that they've gotten all out of your truck.  As we've seen numerous times, there's always room for improvement and performance no matter which year Cummins you drive.  

Let's look at some of the benefits of tuning your 2010-2019 Cummins below:

03-05 Cummins Custom Tuning is Finally HERE!

For over a decade the diesel performance industry has been waiting for REAL custom tuning for their 2003 - 2005 Cummins.  These early common rail engines have dealt with box programmers and pressure boxes for long enough, finally there is a solution.

MM3 Tuning has been out for less than a year and has already made a big splash in the highly modified Cummins world.  With the capability to tune 1998.5 to 2017 Cummins this tuner has a wide range of support.  

However many different reasons there are for the success of this new Smarty based custom tuning platform I dont know, but the 3 reasons below are certainly the most common ones we here at Calibrated Power.
