The Full Delete bundle(s) will permanently upgrade your truck to work without the suffocating factory emissions system.

This means you can remove ALL emissions-related parts and sensors for good, including the:

- DPF (Diesel Particulate Filter)

- DEF tank (Diesel Exhaust fluid)

- EGR System (Exhaust Gas Recirculation)

- CAT (Catalytic Converters, including DOC and NOX, etc.)

This is made possible by our custom delete tunes that wipe away the emissions system from your truck’s computer.

All you have to do is: 

Plug the tuner into your truck’s OBDII port (located under the steering wheel)

Follow the tune installation instructions we sent you. (Tech support is also available).

Once the pesky emissions system is “deleted” from your truck’s programming, you can proceed to remove all of the parts that are holding your diesel back from running at its best.

Our kit includes a DPF/CAT delete pipe that bolts in place of the original DPF and CAT in the exhaust system.

An optional 5" full exhaust system is also available as well as a muffler system.

Lastly, the EGR delete kit will allow you to fully remove the original EGR system, seal shut the openings, and reroute the exhaust to flow out of the pipe.


The EFI Live Bundle includes:

1) EFI Live Tuner and Delete Tune Software (not-preloaded) and all required accessories. Rotary switch to change power levels

2) 4" Stainless DPF & CAT Delete Pipe (all other pipe variants are aluminized)

3) Complete EGR Delete Kit

Optional 5" Full Exhaust System

Optional Muffler System.

The Ez Lynk Bundle includes:

1) Ez Lynk Tuner with Preloaded Delete Tunes and all required accessories. Rotary switch to change power levels

2) 4" Stainless DPF & CAT Delete Pipe (all other pipe variants are aluminized)

3) Complete EGR Delete Kit

Optional 5" Full Exhaust System

Optional Muffler System.


By deleting the factory emission system which has been suffocating your diesel, you’ll immediately notice a night and day difference. It will perform better in every imaginable way, including speed, fuel economy (5 mpg increase on average), and fewer trips to the autobody shop.

Over time, the kit pays for itself with the fuel savings alone. That’s not even considering how many costly trips to the dealer you’ll be saving yourself.

The last benefit is peace of mind, knowing your truck no longer has a ticking time bomb attached to it.


The Major differences are:

1) Monitoring

The EZ Lynk can be connected to your phone using the AutoAgent app.

This will allow you to use your phone as a dash mounted monitor to track multiple metrics at one time.

The EFI Live has no monitoring options, but you may purchase an Edge Monitor device and use that after you install the tune.

2) Preloaded Tunes & Power Settings

The EZ Lynk delete tunes are preloaded, and are a plug and play option. This is most convenient, especially if you are not so techsavvy.

Just download the AutoAgent App (free) to control your EZ Lynk device once it is pluged into your truck's OBDII port.

The Ez Lynk also offers 5 power levels, Hiss and Rumble tunes.

The EFI Live delete tunes are NOT preloaded and will be sent to you via email. You will have to follow our instructions and use your computer to download the tunes into the EFI live device.

Windows 7+ Computer Required

The EFI live offers 4 power settings.

3) Factory Reset

The Ez Lynk will allow you to revert your truck back to factory configuration using the device.

This is just in case you need to put your emission system back in place.

The EFI Live does not have this feature and you will have to flash the truck's ECM back to factory settings at a dealership, should you chose to.

You may be wondering: Which one is right for me?

The answer is: It depends. Both tuners will fully delete your truck and allow the removal all emission components, DPF/DEF/EGR & more.

Both are designed to let your truck run better in street, towing, racing or off-road applications.

Both are very popular.

It just comes down to personal preference

Not tech savvy? Nervous about the software or potentially frying your truck? No worries! With every purchase, we send you a step-by-step instruction guide. Further tech support is also available should any issues arise.

The good news is, our EZ Lynk tuners also come preloaded with your delete tune, just plug it into your truck’s OBDII port and follow our instructions to install your tune.

The EFI live requires more steps, read the tab below.  

And yes, if you run into any technical issues, we got your back. You can contact us anytime and we’ll resolve any issues you may encounter.

To install the DPF delete pipe, you’ll need basic tools you probably already own (things like wrenches, ratchets, etc.). There is no welding required; it is installed using bolts and clamps (which we provide).

All of the pieces of the EGR delete kit are bolt on as well, no welding required. We will email you installation videos for these parts as well.

If you are a complete fish out of water when it comes to working on your truck, we highly recommend hiring a shop to do the install for you.


The tune we create for the EFI Live & Ez Lynk are custom delete tunes.

After purchasing any bundle, you will be emailed a vehicle information form.

Please fill out the form electronically with the information required (Such as VIN, year/make/model, etc.)

We will require this from to be filled out before we ship out your order. If you do not see the email, please contact us.

If you ordered the EZ Lynk, we will ship your Ez lynk with the tunes ready to be installed. Once you install the Ez Lynk to your truck and go through the set up process, your tunes will appear under the ECU profiles.

For the EFI Live, we will send you the delete tune file via email with instructions on how to download it.

If you run into any issues, please open a customer support ticket with our team

Great bundle

Was easy directions and record everything fast! Highly recommend the Diesel Dides!

Randy Moss
Delete kit install

The instructions are kind of hard to follow from the video instructions. A printed copy of the instructions would sure be helpful for a faster reference. Just my opinion. Parts are good so is the helpline.

Marvin Tedder
Quick delivery

The order process was quick and easy. The delivery was faster than expected. Everything looks to be of good quality, will install next week. Stay tuned for more.

Top Notch

Ordered the complete kit with full 5" exhaust for my 2012 Silverado 2500hd from Diesel Dudes. They answered all my preliminary questions before I ordered so that I could order with confidence. Their communication is very prompt and my components came very quickly in 3 shipments just as described. I followed the details of their instructions exactly and installed the EZ Lynk program on my ECM with zero issues. I also removed and installed all of the exhaust components in my garage with no power tools at all. It took me about 4 hours by myself, but could have easily been done in less with a helper. After the install I had some technical tune questions which were always answered very quickly. I will do the EGR delete soon and have full confidence that it is exactly what they describe.
The first week results of driving shows about a 5mpg increase (small town driving) with my 0hp tune and about 6mpg on highway.
No more worries about warning lights and limited driveability due to unknown and costly emission issues.
Love my truck!! Thank you Diesel Dudes!!

Clay McKinney
Looking back it wasnt so bad

This is certainly a job most anyone can do if they have the determination. In my case, 2012 Duramax, the EGR cooler was a pain to remove. Instructions state to remove the front bolt attachement, however was unable to remove all bolts. Then instructions advise to remove the middle bolt attachements and that was not doable either. Found it best to skip straight to the downpipe and remove the back four. I spent hours on the EGR cooler and knowing what I know now I could have saved many hours doing so.

Buy a vertical creeper!!!

The parts and the tune are of high quality and my next diesel will have a diesel dudes tune kit.
