The 6.7L Cummins engine is a beast, but due to factory components, such as the DPF, it’s true capabilities are held back.
Well, what if I told you that removing the DPF not only gets more power out of your truck, but also gets better fuel mileage.
Removing the DPF (also the EGR) systems allow your truck to “breath” much easier.
This is because factory components recirculate the exhaust fumes, which eventually leads to soot buildup.
So if you remove these components, the engine produces power more efficiently, which means less fuel will be used.
The free flowing air also allows the turbos to function better, meaning better throttle response and more power output.
Below we will review the parts you will need for a complete delete on a 6.7L Cummins engine.
The Best 6.7L Cummins DPF Delete Tuner EFI Live Autocal V3 | DPF Delete Tuner | Dodge Ram 6.7L 2007-2018
Before you delete any components, you first need a DPF/EGR delete capable tuner.
This is essential as your truck’s computers will run codes and run into many problems if you remove your DPF/EGR.
That’s where the tuner comes in: It programs the truck to operate with those components removed.
You can’t just use any old tuner though, you have to make sure it comes with delete tunes installed on it.
The EFI Live Autocal V3 comes equipped with 5 power levels: +20HP | +40HP | +60HP |+80HP | +100HP. It also is shift on the fly compatible, meaning you have to switch between these power levels anytime, with the use of a switch.
The EFI Live also clears all diagnostic codes, includes tune revisions (in case you change your tire size) and has full tech support.
For these reasons, it is hands down the best DPF delete tuner for a 6.7L Dodge Cummins.
If you are more budget concerned, have no fear. The H&S Mini Maxx is the best bang for your buck delete tuner.
And luckily, it’s compatible with 6.7L Cummins (NOW UP TO 2021!).
Not only is the H&S Mini Maxx a budget friendly alternative, it’s actually full of features that more expensive tuners don’t even include.
And it’s all ready for use, right out of the box, no additional installs needed! The Mini Maxx also has a gauge display and includes a diagnostic scanner.
No wonder it is our best selling delete tuner.
DPF Delete Pipes
Ok so we covered tuners, but now let’s review DPF delete pipes.
The delete pipe will replace the section of your exhaust where the DPF filter resides.
This creates a straight connection from the turbo back to the muffler. Note: That means you retain your factory muffler.
If you want a muffler delete, you will need to purchase a full exhaust system.
Once you install a DPF delete pipe, you must have the delete tune installed. Otherwise your truck’s computer will throw codes and put it into limp mode.
If you want the maximum performance gains, opt for the full exhaust system.
These systems are mandrel bent and have a wider diameter, allowing for maximum exhaust flow.
But, if budget is a concern, the delete pipe will do just fine.
And yes, DIY is straightforward so long as you have basic hand tools and enough space.
These pipes include all required hardware and come with factory style hangers. Installation instructions are included in the purchase and there are many helpful YouTube videos if you get stuck.
EGR Delete Kit
When you install an EGR delete kit, you are removing your EGR and bypassing your cooler.
This gives you lower running temperatures, improves throttle response, much better fuel economy and increases reliability.
Our EGR kits are CNC machined from high quality air-craft 7075 aluminum and designed to fit perfectly.
