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.

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.

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.


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.

Easy install. Great tunes!

2015 Duramax

Bought the truck with a new engine, fuel system, and turbo. It had a delete kit and needed tuned. I had to figure out what was deleted. The truck had codes that required an ECM update from factory. Once that was done, I tuned the truck with the EFI live. Once complete, the truck ran like a champ and no more codes!!

Jake Clark
It's ok

I actually like the V2 better more user friendly

Steven Smith
Happy customer

Just installed me efi live dsp5 tunes and couldn't be happier. I haven't installed the switch yet bit with just the stock tune my truck feels like a completely different truck. It got ride of the awful duramax throttle response. Can't wait to see what the other tunes feel like
