Are you looking to get more power and get better fuel mileage from your 6.7L Cummins powered truck? On this page I cover just how you can do that, by outlining the parts required for a complete DPF and EGR delete kit.

Removing the DPF and EGR systems allows your off-road truck to breath much easier and run much more efficiently than it does being held back by a defective factory emission systems.

Below is the list of required parts that you will need for a complete delete kit for a 6.7L Cummins engine, as found in the 2007+ Dodge diesel trucks.

One warning first though: if you plan to operate your truck on roads in the United States, your emissions systems have to be operational. Deleting emissions systems is for off-road use only. If you live in a country where this is not a concern, read on to find out the parts you’ll need.

Best Cummins 6.7L DPF Delete Tuner

• RaceME ULTRA DPF Delete Programmer 07.5-16 Dodge Cummins 6.7L

When looking for a tuner for performance diesel tuning and DPF/EGR deletes, you need to make sure that the tuner you choose is actually capable of working with your diesel truck’s computer to remove the codes that are associated with DPF and EGR removal.

You can find a lot of different tuners available for the 6.7L Cummins, however there are only a few tuners that have the ability for a true DPF and EGR delete.

H&S and RaceMe are the best available tuners that have this capability for the 6.7L trucks. Both of these tuners can delete the DPF and EGR codes, with a custom tune.

DPF Delete Pipe

A race exhaust will replace the section of pipe where the DPF filter currently resides and gives the exhaust a straight shot from the turbo back to the muffler.

It is crucial to have the tuner installed with this delete pipe, otherwise you will throw the truck’s engine computer into limp mode because it won’t be able to use the sensor readings to initiate regen anymore.

Installation is fairly straightforward, usually the hardest part of replacing exhaust is super-heated rusted hardware, in some cases requires heating or cutting of exhaust studs, make sure to have a torch handy!

This Monster-Ram kit from Banks drastically opens the airways from the intercooler directly into the engine. It can flow up to 1008 cfm (77.01 lbs/min) compared to Stock's measly 432 cfm (33.00 lbs/min).m Allows for an increase in boost without increasing backpressure at the turbine. Result: a more responsive, power efficient engine. Up to four 1/8 inch NPT ports for flexibility! The top two NPT ports are positioned to allow for proper atomization directly into the center of the air mass while preventing wall wetting. Accommodates stock mounting points including Temperature and Pressure sensors, wire harness and dipstick tube. At Banks Power, just enough is never enough when it comes to engine airflow. Maximum power, performance and efficiency are the ultimate goals, but to make it all happen the engine has to breathe freely and without needless restrictions. Finding ways to pump your engine full of cooler, denser air has always been the key.

Good news! Just like their predecessors, the 2010+ Ford diesels respond excellently to a good tune.

If you’re looking for the ultimate tuning and performance package for your 6.7 Powerstroke engine, look no further for all the parts you’ll need to pull it off.

We’ve created this guide to highlight the best options available for deleting the DPF and EGR on your truck, as well as the best option for a tuner that can handle the ECM as well.

Just a few parts are all it takes to start exploring the whole new world of power and economy possibilities of tuning your 6.7L Powerstroke.

Of course, there’s new rules to this game. New technology in truck engine management and more restrictive emissions requirements are two main barriers that you have to overcome when tuning these trucks.

Let me be clear right off the bat though, if you live and drive in the United States, be aware that these modifications are for off-road use only.

However, if you live in another country without the same regulations on emissions, you would be doing a disservice to your truck if you didn’t ditch the dead weight.

In this guide, we’ll show you how to get more power and better mileage out of your LML Duramax diesel equipped truck, by putting together the parts you’ll need for a full DPF and EGR delete and tune.

The main objective is for your truck to reach its maximum tire-frying (or fuel saving) potential.

Deleting the failure-prone DPF and EGR emissions systems will allow your truck to breath a lot easier and run more efficiently, all without having the worry of inevitable factory emissions equipment failure.

One thing to be aware of though, if you live in the United States and want to continue to drive your truck on public roads, you need know that delete tuning is for off-road use only.

If you live in a country that doesn’t have such restrictions though, and want to get the maximum potential out of your truck, you will find that there are a ton of parts available for deleting the 2011-2016 LML Duramax, and just as many choices on how to go about tuning it.

Lots of different parts can get us from A to B in the delete roadmap, but there are some that stand out from the rest, and we’ll go over the what part and the why in this guide – starting with two tuner options that are both delete capable.

The cheapest delete tuner for the LML Duramax

• H&S MiniMaxx DPF and EGR Delete Race Version

The powertrain control systems in modern trucks are so heavily tied into the emission system, when you try to run without these systems installed you’ll end up just throwing the engine computer into limp mode. This kills your mileage and performance, unless you have a way of controlling the engine computer to edit those functions out.

One of the biggest requirements, and the first thing to look for in a tuner, is if it actually has the ability to actually delete the DPF and EGR systems. You’ll really want to make sure the tuner you get can do this, as there are some tuners out there that aren’t actually capable of programming the PCM to delete the factory emissions systems.

The good news is that the H&S MiniMaxx Tuner does allow you control over the emission systems, and more. It’s not going to be able to push the limits of modern tuning technology, but it will definitely be able to allow you to delete the DPF and EGR and load up a pre-made tune for more HP or better mileage.

Perhaps it’s best feature is how easy it is on the wallet, compared to the more modern tuners. It does give good value per dollar in how much it can improve your truck over stock.

• EZ-Lynk AutoAgent

If you need more capability from a tuner, or if you want a tailored tune to squeeze the most out of your Duramax and it’s transmission, look no further than the EZ-Lynk.

This little guy takes the tuning of your Duramax to a whole new level. It’s basically the future of tuning.

You may notice that it doesn’t look at all like a traditional tuner, it completely lacks any sort of screen or buttons. This is because the EZ-Lynk is controlled completely by your smartphone.

It works with Apple and Android phones, which gives it the ability to have what I believe to be one of the coolest tuner features I’ve ever seen: the ability to sync wirelessly with the EZ Lynk’s tuning “cloud” software.

That means that you can upload information directly from your truck to your preferred custom tuning shop, and they can use that info to build your truck a truly personalized tune. All without having to bust out the laptop, which is pretty awesome in itself.

It does cost a bit more than the entry-level H&S, but it makes up for it in features. The tune support from GDP is the best option for nailing down the perfect tune for your truck, and the optional DSP5 switch allows you to switch between tunes on the fly (SOTF) which is an awesome feature.

• LML DPF Delete Pipe

Replacing the section of the exhaust that normally contains the DPF is easy when you use a complete exhaust kit like this straight pipe system.

This exhaust kit comes ready to bolt directly to your downpipe and gives your turbo a straight shot directly out the back of your truck. As you can imagine, a straight shot without all the restrictions of the honeycomb DPF filter not only sounds better, it flows way better than before. Naturally, less restrictions = more power and more efficiency.

This exhaust kit works perfectly for deleting the LML trucks – even with different bed and cab configurations, although some of the shorter length models need to trim it down to fit.

• LML EGR Delete Kit

An EGR delete kit is actually sometimes more of a preventative repair item for LML duramax engines, because of how clogged the system gets.  I see a lot of people having to do repairs on almost the entire EGR system over the trucks lifetime.

Why not just get rid of the headache altogether. That’s where this kit comes into play.

Now, it’s true that the EGR function can be edited out of the ECM with a tuner, and the EGR valve kept in its place, in which case you wouldn’t need a blockoff plate. There’s a possible failure when you do that though, the boost pressure from the turbo can still overcome the EGR valve even if the function is turned off, causing exhaust gasses to leak past the valve and into the intake.

This blockoff kit eliminates that issue and ensures that the exhaust gasses cannot enter the intake tract at all anymore.

If you’re wanting to tackle the install of this kit yourself, or if you’re looking for more information about EGR deletes for the LML, take a look at the install portion of this post.

• LML DEF/Urea Tank Delete

After you tune the emissions requirements out with a delete tuner, and replace the exhaust to remove the DPF and DOC, you can then remove the terrible eyesore that is the DEF tank. This tank, if you hadn’t noticed, sticks out under the frame on the passenger side of your truck.

Simply undo the sensors and filler, then unbolt the tank straps to get this plastic pee jug off your truck. No more worrying about filling the urea.

We hope this guide was helpful to you and gives you some direction on which parts you’ll need to put together and tune a full DPF and EGR delete package for your 2011-2016 Duramax.

Oh and just for fun, here’s a clip of what the exhaust  noise sounds like coming from a tuned LML truck:

Want to add about 150HP and get an average of 5 MPG more in fuel mileage out of your LMM Duramax?

If emissions aren’t a concern for you, then adding the HP and mileage is as simple as deleting the DPF and EGR from your truck. Be aware that these modifications are only for off-road trucks in the US, or for countries without these regulations.

Removing these highly restrictive and failure-prone systems allows your truck to breath much easier and run much more efficiently.

Below I’ve compiled the list of required parts that you will need to delete the DPF and EGR systems on your LMM Duramax engine, as found in the 2007-2010 GMC/Chevy diesel trucks.

DPF Delete Tuner

When adding performance or deleting systems on your LMM, the first thing that you’re going to need is a good tuner.

There are a lot of tuners that can help with different tunes for fuel consumption, horsepower and towing modes, but there are only a couple options for race tuners that are able to unlock your truck for the real power and reliability of deleting the DPF/DOC and EGR.

This is the best option for the LMM Duramax for a truly out-of -the-box delete capable tuner:
