6.7 Cummins Upgrades

Written By: ProSource Diesel

The world of aftermarket diesel truck parts is vast with plenty of options to upgrade your 6.7 Cummins truck. Cummins performance parts can add power, efficiency, reliability, and even better gas mileage in some cases. The stock 6.7 Cummins engine is undoubtedly a great engine, but there’s plenty of room for improvement. Increase your truck’s horsepower, torque, and even its lifespan with 6.7 Cummins upgrades.

Check out this ProSource guide for some of the best upgrades for your 6.7 Cummins truck.

Section One: Upgrades for 2007.5 – 2012 Cummins

The 24 valve 6.7-liter Cummins diesel launched in the middle of 2007. It featured 650 pound-feet of torque when equipped with an automatic transmission and 610 pound-feet of torque when equipped with a manual transmission. The torque amount was purposely decreased for the manual. By 2012, trucks with an automatic transmission created 800 pound-feet of torque. The 6.7-liter Cummins also came with a DPF or diesel particulate filter in accordance with EPA standards.

The upgrades featured in this section are aimed at increasing your turbo power and cooling capacity as well as adding performance tuning.

This is one of the most important Cummins upgrades for increasing turbo airflow and compression, which results in more power and cleaner running. The stock compressor wheel is known to have flaws that create issues with surging and lag on initial acceleration. The Spoologic kit corrects boost limits by 5-7 PSI as well as improving performance at higher boost levels.

BanksPower Intercooler Upgrade Kit For 2007.5 – 2012 Cummins

This kit upgrades your stock intercooler system with larger boost tubes, tanks, inlet and outlet, and a thicker core. By upgrading to this larger, more efficient cooling system your engine gets increased cooling capacity due to the colder, denser air entering the engine, plus an overall increase in airflow. Denser air provides more oxygen, which makes combustion more efficient. That means more power, lower exhaust gas temperatures, and overall better fuel economy.

One of the best ways to increase performance in your 6.7 Cummins is by using a tuner. This particular tuner is an in-cab tuner with a full-color, high-resolution monitor so you can easily read diagnostic codes and stats like the following:

– Barometric pressure

– Engine speed

– Engine coolant temp

Fuel rail pressure

– Transmission temp

– Manifold air pressure

– And much more!

Max power gains for specific 6.7 Cummins trucks with this tuner are:

– 2007.5-2009 Dodge 6.7L Cummins: +125 HP +340 lb-ft

– 2010-2012 Dodge 6.7L Cummins: +95 HP +270 lb-ft

Section Two: Upgrades For 2013 – Present Cummins

Starting in 2013, the Cummins 6.7 underwent some tweaks, which included a fully redesigned cooling system for Ram Heavy Duty trucks. The new system included dual radiators and transmission coolers, which increased heat rejection by 25 percent.

The upgrades in this section aim to increase your turbo boost system power and the cooling capacity of your 6.7 Cummins.

Aftermarket intercoolers are one of the best upgrades you can make towards extending the life of your Cummins engine.

Section Three: Upgrades for Both Cummins 6.7 Models

The mods in this section are made to fit both the previous generation of 6.7-liter Cummins and the second generation that includes engines made from 2013 until now. These upgrades are aimed at increasing efficiency and reliability in your Cummins truck.

The AirDog system uses a pump shaft that keeps the electric motor away from the fuel. This keeps the motor from getting wet in the event of a damaged or leaking seal.
