NO MORE EMISSIONS CODES

+ -

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

BENEFITS

+ -

By deleting the factory emissions system that’s been suffocating your diesel, you’ll notice a night-and-day difference right away.

  • Better performance: your truck runs better in every way, starting with throttle response.
  • Better fuel economy: an average 5 mpg increase.
  • Pays for itself: over time, the fuel savings alone cover the cost of the kit.
  • Fewer shop visits: no more costly trips to the dealer for emissions repairs.
  • Peace of mind: your truck no longer has a ticking time bomb attached to it.

TUNE POWER SETTINGS

+ -

Our custom tunes include multiple power levels, so you can run your truck the way you want. You can change between levels in real time (also known as “shift on the fly”) using your truck’s steering wheel controls. We’ll email you a simple 2-minute video showing how after purchase.

MPVI4 power settings:

  • Level 1 (Stock): no added HP. Ideal for daily driving and towing.
  • Level 2: +50 HP. Ideal for daily driving and towing.
  • Level 3: +80 HP. Ideal for daily driving and towing.
  • Level 4: +130 HP. Ideal for performance applications.
  • Level 5: +200 HP. Ideal for performance applications. Results can vary by about 20 HP depending on whether you have a cold air intake and full exhaust.

Available power levels depend on your truck’s year.

WHAT'S INCLUDED?

+ -

The bundle includes:

  • MPVI4 delete tuner with our custom delete tunes and shift-on-the-fly software
  • Tuning unlock tool
  • CAN plugs
  • Stainless steel DPF/CAT delete pipe
  • Complete EGR delete kit

Optional add-ons:

  • 5" stainless steel full exhaust system upgrade

HOW DOES IT WORK?

+ -

The GM/Chevy Duramax 6.6L L5P Full Delete bundle 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:

  • DPF (Diesel Particulate Filter)
  • DEF Tank (Diesel Exhaust Fluid)
  • EGR System (Exhaust Gas Recirculation)
  • CAT (Catalytic Converters, including DOC and NOx)

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

How it works

  1. Plug in the tuner. Connect it to your truck’s OBD-II port, located under the steering wheel.
  2. Load the tune. Follow the installation instructions we send you. Tech support is available if you need a hand.
  3. Remove the parts. Once the emissions system is “deleted” from the programming, you can remove everything holding your diesel back.

What’s in the kit

  • DPF/CAT delete pipe: bolts in where the factory DPF and CAT were.
  • EGR delete kit: lets you remove the factory EGR system, seal the openings, and reroute exhaust out the pipe.

IMPORTANT INSTALLATION INFORMATION

+ -

Not tech savvy? Nervous about the software or frying your truck? No worries! Every order comes with a step-by-step instruction guide, and if you run into any issues, we’ve got your back. Contact us anytime and we’ll get it sorted.

  • Tuner: installs with a laptop. After purchase, we’ll send you a video showing how to use the ECM upgrade kit, your laptop and the HP Tuners device to install our custom delete tune.
  • Laptop requirements: a Windows PC running Windows 7 or newer. Mac and Linux aren’t compatible.
  • DPF delete pipe: bolts on with the bolts and clamps we provide. No welding, just basic tools you probably already own, like wrenches and ratchets.
  • EGR delete kit: also fully bolt-on with no welding required. We’ll email you installation videos for these parts.

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

HOW TO SEND US YOUR VEHICLE INFO

+ -

Every tune for this bundle is one of our custom tunes, built specifically for your truck, so we need a few details from you first.

  1. Check your email. After you purchase, we’ll email you a vehicle information form.
  2. Fill out the form. Complete it online with the details we ask for, such as your VIN and your truck’s year, make and model.
  3. Submit it. We need the completed form before we can build your custom tune and ship your order.

Don’t see the email, or running into any issues? Open a support ticket and our team will help.

DOWN PIPE INFORMATION

+ -

Optional add-on: add a 3.5" turbo downpipe (also called a turbo direct pipe) to your order. It isn’t required for the delete kit or the delete tune to work.

Why add it: the DPF delete pipe and full exhaust systems don’t remove the DOC (Diesel Oxidation Catalyst). This downpipe does, so it’s the piece that completes a full emissions delete. Some downpipes start behind the DOC and leave it in place, but this one removes it completely for the best airflow and power gains.

Features:

  • Piping: 3.5" stainless steel
  • Flow: 20% better than the factory pipe, built for maximum flow in competition applications
  • Heat wrap: included, to keep engine bay temperatures down and hold heat in the pipe
  • Mounting: 4-bolt flange with two studs installed
  • DOC delete: completely eliminates the DOC
  • Removed line: I dropped “Will not affect emissions systems”. It contradicts the rest of the tab, which says this pipe removes the DOC.
  • Merged lines: the two heat lines (“heat wrap keeps engine bay temperatures down” and “greater heat retention”) are now one Heat wrap bullet. The flow and competition lines are combined the same way.
  • Labels: each feature now has a bold label, matching the other tabs.

NO NEED TO SEND IN YOUR ECM!

+ -

Your kit includes the E41 ECM Upgrade Kit by HP Tuners, so there’s no need to buy and install an unlocked ECM. That keeps your cost down and makes the install simple.

Installation: about 20 minutes when you follow our step-by-step video guide, which we’ll email you after purchase.

SHIPPING & RETURNS

+ -

Processing

Right after you complete your purchase, we’ll email you a vehicle information form. We need it before we can build your custom tune, so processing starts once you submit the form. Processing takes 1–2 business days, and then your kit ships.

Shipping

  • Standard: 5–8 business days
  • Express: 3–4 business days, for an additional $199 on this bundle ($299 with the 5" exhaust)

Alaska, Hawaii, and some Canadian locations are subject to additional freight charges.

Returns

Each item in this bundle has its own return policy, so please read carefully:

  • MPVI4 delete tuner, tuning parts and ECM upgrade kit: built to order, so they aren’t eligible for refunds or cancellations. We guarantee the tuner will work, and if you receive a faulty or damaged tuner, we’ll replace it.
  • Exhaust systems and DPF/CAT delete pipes: final sale and not eligible for a refund or return. If you receive a faulty or wrong product, we’ll send you a replacement.
  • EGR delete kit: returnable within 30 days of purchase if unused (never installed on your truck). You’re responsible for return shipping, and there’s a $30 restocking fee.

The GM/Chevy Duramax 6.6 L5P Full Delete Bundle permanently upgrades your 2017-2023 L5P to run without the factory emissions system. Once the delete tune is in, the emission-related codes stop, including "See Dealer" codes, check engine lights, "Exhaust system service required" alerts, and limp mode.

It works through custom delete tunes that wipe the emissions system from your truck's computer, which lets you remove the DPF, the DEF tank, the EGR system, and the CAT (including the DOC and NOX) for good. A Windows 7 or newer PC is required for tune installation, since Mac and Linux aren't compatible, and instructions are emailed after purchase.

In the bundle you get a tuning unlock tool, delete tuning with Shift on the Fly, CAN plugs, your choice of a DPF/CAT delete pipe or a 5" full stainless exhaust, and a full EGR delete kit. It also includes the brand new E41 ECM Upgrade Kit by HP Tuners, so you no longer need a separate unlocked ECM. Tune installation takes about 20 minutes with the included video guide, and an optional 3.5" stainless downpipe add-on fully removes the DOC and flows 20% better than the factory pipe.

The tune carries five power settings: Stock, +50HP, +80HP, +130HP, and +200HP, and you change levels using your steering wheel controls. Most owners see a 5 mpg increase on average. After purchase you'll get a vehicle info form to complete before we ship. On returns: exhaust and delete pipes are final sale, the EGR kit is returnable unused within 30 days with a $30 restocking fee, and the rest of the kit is non-refundable.

For off-road/competition use only.

Frequently Asked Questions

Didn’t find what you were looking for? Reach out below!

A Full Delete Kit removes all emissions components that commonly fail—DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and DEF (Diesel Exhaust Fluid) systems. Our kits include the tuner, delete pipes, and any required sensors or block-off plates—customized for your truck’s make, model, and year.
Most of our customers install the kit themselves with basic tools in a garage or driveway. Average install time: - DPF pipe: 1–2 hours - EGR delete: 2–4 hours - Tuning: 20–40 minutes We include guides and offer full lifetime support.
Our custom tuning disables all emissions-related codes, CELs (Check Engine Lights), and regen cycles. Once the tune is installed, the truck will stop trying to regen or enter limp mode.
Delete kits are for off-road and race-use only. They are not legal for highway use in the U.S. or Canada, especially in states with strict emissions laws (like California). Many customers in rural areas or provinces without emissions testing still choose to delete for reliability and performance.
Many customers opt to electronically disable the EGR without physically removing it, especially for a cleaner engine bay or quicker install. Our tuners support both full deletes and “leave-in-place” disable setups.
Yes. Most customers report a gain of 2–5 MPG depending on driving style, tune level, and truck setup. You’ll also eliminate DEF refills and regen cycles, which further saves fuel.
No cutting or welding is needed for most applications. Our pipes bolt up directly to factory locations and use existing mounts and gaskets. We make it easy to return to stock if needed.
Deleting the DPF will make the exhaust louder. You’ll hear more turbo spool, engine tone, and exhaust note, especially with a straight pipe. We offer optional mufflers for those who want a quieter ride.
We’re not just a parts store—we’re diesel truck owners too. Here’s why customers choose us: - All-in-one bundles, no guesswork - Lifetime support with install help, updates, and tuning questions - Fast shipping and transparent pricing - Trusted by thousands of truck owners across North America.

Great kit!

Everything went to be expected, tunes are amazing and really woke the truck up. Only negative thing I ran into was one of the coolant lines being to short.

ALMOST 5 Star

I have now put a few thousand miles on this kit and have taken care of the little kinks and trust it 100% now. I want to give this a five star review very badly but for the money spent, there are a few minor details with the kit that I believe should be improved. First I want to say that the customer service is great and overall the kit if very easy to install and follow. The exhaust installation and the CAN plug locations should have better instructions, very minor gripe and it’s pretty easy to figure out with a little common sense and maybe some googling, but for cost, I believe that information should just be provided in the instructions provided. The minor yet major problems that I ran into with the kit was the cheap fitting provided to replace the OEM heater inlet and the small piece of capped hose that goes over the nipple that is no longer needed on the coolant hardline. Both separate occasions of these parts failing caused me to dump roughly 4 gallons of coolant each time. So on top of the 100ish bucks you already spend on coolant when performing the delete, I had to go and spend roughly 200-220 dollars more on coolant when the parts gave. I ended up making my own fitting for the coolant line and recently ended up buying the Dorman Billet heater core adapter piece. Other than that, this kit has been absolutely awesome and seriously wakes the L5P up. I hope that this will be taken into consideration by the Diesel Dudes and they will have better parts implemented into the kit in the future making this 100% a 5 star kit.

Breathing so much better

Took two an half days had to get it together but got held up because there was not a T so had to hold off till Monday morning till the hardware store opened up. But overall was a success and a very happy customer will be spreading the word for anyone in my community with there L5Ps thanks diesel dudes, and J.Tingle for the help.

Feels like a new truck

Instructions were top notch, parts were even better! There are only 3 cons I must share, I got the fabricated 3.5” down pipe and I wish they had given a longer piece of heat wrap. The second is maybe supply the heater core line tool to remove the line off the firewall. Thirdly was the hardware for one of the block off plates almost got me. Did not overtorque it, used a snap on digital torque Wrench and the bolt almost broke in half. Other than those the kit is flawless. 5 stars

Great instructions and support!

Do yourself a favor and go get better fittings for coolant lines and a better plug for off the turbo feed line. I’ve had both larger coolant line and the plug fail. Just bought a 3 ply plug and stainless heater core connection and had to replace oem o-ring off the other heater core hose. But other than that extremely satisfied with everything so far! This will take a few days alone just an FYI I had a buddy with me and it took 20ish hours I bet!

L5P Full Delete

Awesome kit! The customer service was great, the shipping was fast, and has me saying the same thing everyone else says after a full delete.. should have done it sooner. Nothing wrong with the kit but I will say on my 2019 L5P I had an issue with my Turbo Pedestal, it wasn't causing any problems but when removing it I found it was warped and needed to be replaced so I had order it and wait for it to come in. So if installing the downpipe ( highly recommend ) maybe order one ahead of time or trying leaving the Turbo in place and just lifting the cab to remove the SCR.

Great Kit!

Kit had everything needed to do the delete, it was all packaged well, and came quickly. Tuning was simple following the directions, no issues at all. I would recommend you get your own heater hose, as the ones in kit could be a bit longer, I used my own hose. Other than that, good buy. Truck runs like a raped ape!

J
Jayson Wompler
As was expected.

I will be putting the exhaust on tomorrow but everything went well thus far. The videos were amazing. I did however run into the same issues with the length of the supplied heater hoses. I didn’t as he did in the video and went and bought some. Tune was very easy to do with the instructions and videos. Once again as he stated in the video, after tuning I encountered a check engine light that I had to clear. So far so good. Small items that maybe could be explained to the customer but a 5 star review was given since everything g else went as planned.

Amazing kit! Super easy installation and easy to follow instructions. Very simple plug and play kit. I have minimal wrench turning experience but was able to do this no problem. Will be using them again for the wife’s truck, and the father in laws truck as well. Amazing product and worth every penny.

Quality product

Definitely a quality product, Although I did have some issues. After the install was completed or nearing the end I realized I was missing some of the hose plugs and hose barb that connects the turbo to the coolant line and the clamps. Also missing some electrical plugs for the Def tank harness. It was little things that were on me for not doing a full inventory when product arrived for the little things.

Some improves
-When flashing ECU I had a discussion with the tech on the phone and I was told I needed to use the VCM BETA software or run the risk of frying my ECU using the VCM (stable version) because it’s for “gas vehicles”. If this is true it needs to be clearly stated somewhere because people are more likely to use stable software to avoid issues.

Printed instructions would be nice with an inventory sheet with all the parts just so people don’t have to watch a YouTube video. Especially with the year differences

Tech on the phone Tyler answered all the questions I needed however either lacked interpersonal skills or was miserable
