EFI Live Autocal V3 for GM/Chevy Duramax 2001-2016 | Delete Tuner

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.

Steps:

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.
