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 full exhaust system that replaces your factory exhaust, as well as the DPF/CAT.

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.

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

2) 4” Full Exhaust System

3) Complete EGR Delete Kit

Optional Muffler System.

These power settings correspond to the 5 levels on your DSP5 Switch.

Level 1: "Stock" 0HP. Ideal for daily driving, towing.

Level 2: +40HP. Ideal for daily driving, light towing.

Level 3: +65HP. Ideal for daily driving.

Level 4: +100HP. Ideal for performance applications.

Level 5: +130HP. Ideal for performance applications.

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.
