When you install the delete tune, your truck will no longer have emission related codes or warnings. 

This includes all

1) “See Dealer” codes

2) Check engine codes

3) “Exhaust system service required” codes

4) Limp Mode codes

5) Other emissions related diagnostic codes


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 kits 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 EFI Live delete tuner 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.


You will then use the EFI Live V8 software (Free to install) to download the delete tune from your computer to your EFI Live device.

We will provide basic instructions on how to do this, but please be aware, a Windows 10+ Computer Required is required, no Macs or old PCs.

After your download the delete tune into your EFI Live device, plug the EFI Live into your OBDII port (under your 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.

You will need to install a DPF Delete Pipe after you install this tune.

(The only exception are the older Duramax models that do not have a DPF)

You can find the DPF Delete pipes and exhaust systems here

If you need a full delete bundle, that includes this tuner, delete pipe and egr delete, find it here.

All Cab & Chassis trucks only come with a single tune file and not DPS5.

It is a +50HP tune.

A Cab & Chassis truck is one that says "Incomplete Vehicle" below the VIN on the registration sticker, typically found on the driver door.

Most Cab & Chassis trucks are the 4500 and 5500 models.

If you have a Cab & Chassis model with a single fuel tank, please contact us before purchasing as certain model years are not compatible.


The 2011-2016 LML comes with either a Electronic Transfer Case or a Manual.

The trucks that have a Manual Transfer Case are not compatible with DSP5 tunes and will only receive a single +50HP tune.

If you turn a dial or push a button to put your truck into 4x4, you have an Electronic Transfer Case and will received DSP5 tuning.

If you pull a manual lever, you have a Manual Transfer Case.

It’s gonna be wild!!

My truck is currently down so when it’s up and running again the Autocal is definitely going in!!

Samuel King

Ordered EFI Live tuning and 5” exhaust. Install was pretty straight forward with exhaust and tuning. There is plenty of videos online that show how to complete the process for a LML. They also send you instructions on how to do everything. Shipping took about 8 days to get everything, tuner came first and then the exhaust. Sounds great, runs even better and no longer have to deal with DEF and other emission BS. Customer service is outstanding as well. Highly recommend these guys for tunes/delete. PS I wish it came with some stickers.

Grate job

My order came in like they said, and it was easy install and my truck runs way better and has a lot more power I definitely give the diesel dudes a five star rating will definitely be doing more business with them

Ronnie Norquist
