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!

Smarty MM3 Tuning Update! 

We have been testing the new Smarty MM3 Tuning for the 1998.5 - 2016 Cummins. The software/hardware is the newest solution for custom tuning.  Until now, the  limited amount of accessible tables in the 1998.5-2002 tuning platforms made fine tuning challenging for highly modified Cummins trucks leaving them smokey, noisey,  and generally not as smooth as other similarly modified trucks tuned with more advanced software.  Now that we have access to said tables, we will be able to create clean, efficient power with these trucks.

One of the most exciting features to the new Smarty MM3 is Live Tuning.  The live tuning ability allows our tuners to make real-time changes to the calibration on the dyno or during a road test where in the past we had to wait 7-12 minutes to implement one change.  As you might imagine, live tuning will significantly shorten the developement cycle and allow us to quickly  fine-tune a wide variety of modifications on-site at CPS.   The second advantage to the live tuning software is the ability of the customer to change tunes (power levels etc.) on the fly on any of the supported platforms.  These power levels will be supplied along with the base tune to customer at the time of sale (idealy).  

Our discussion with the developers of this software/hardware package lead us to believe that improved scan tool functionality is next on the priority list.  We would expect to see a very high sample rate scan tool along with several dozen of the most important PIDs in the near future for beta testing.   This tool is critical to the development process.  Without a strong scan tool we cannot validate our work, the better the tool - the better the final product and the better we can help our customers troubleshoot accurately if they need to.

Tuning your 2010-2015 Cummins can dramatically improve your driving experience!

The Dodge/Ram/Cummins manufacturers have improved many factors that impact your driving experience throughout the years. From cup holders and radios and interior cab lights to heated seats, larger mirrors and automated turbine braking; Cummins trucks are getting better every year. Horsepower and Torque have not been missed in these constantly ongoing improvements. Back in in 1989 the first 12v had just a 160 RWHP rating from the factory, now the 6.7L as off 2010 is 350 - 370 Horsepower depending on transmission and trim package. With that being stated, there is still a lot of room for aftermarket tuning to improve your truck. 

Below are 7 things you shoud know, before you decide which tuning is right for you . .  . .
