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.

Many truck owners that have a Cummins powered Ram equipped with an Aisin transmission have inquired about transmission tuning and performance upgrades.  Although at this time Aisin transmission tuning is not available, we have had excellent results with the increased drive-ability of the trucks. 

Recently we worked with Jim McNicoll to tune his 2016 Ram equipped with a Aisin transmission with our Custom MM3 Tuning.  Below you will find his review of the tuning and the process.

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.
