Product Information
The LMM Duramax Full Delete Bundle for 2007.5–2010 GM/Chevy Sierra and Silverado permanently upgrades your truck to run without the factory emissions system. Install the delete tune and the "See Dealer" codes, check engine lights, "Exhaust system service required" alerts, and limp mode codes are gone — and you can pull the DPF, DEF tank, EGR system, and CAT (including the DOC and NOX) for good.
Custom delete tunes do the work in software, then you remove the hardware. The bundle includes an EFI Live tuner with delete tune software and all required accessories plus a rotary switch, a 4" or 5" full exhaust system, and a complete EGR delete kit. An optional muffler system is available. One install note specific to this platform: on the 4" and 5" exhausts the front hangers aren't used — the exhaust is supported without them.
Power runs through the DSP5 switch with five levels: Stock (0HP), +30HP, +65HP, +100HP, and +130HP. The tunes are not preloaded — after purchase we email them, and you load them onto the device with the free EFI Live V8 software. That requires a PC or laptop running Windows 10 or 11 (no Mac or Linux), one USB port, and at least 1GB of free space. Basic computer skills do the trick. Most owners see around a 5 MPG gain.
Fits 2007.5, 2008, 2009, and 2010 Sierra/Silverado 2500 and 3500 with the 6.6L LMM Duramax, all pickup trims. Won't fit Cab & Chassis — call (888) 830-2588. Standard shipping 6–10 business days, express 4–6 for $299.
For off-road/competition use only.

The Delete system got to my home quick, and was well packaged, everything came in great shape. Once I was able to find the right videos and instructions I was able to do the Delete and install on my own mostly, by reading the instructions and watching videos. There wore some things I had to call in for assistance, like what to do with old sensors, and what some of the things wore for that coming in my order, my all my questions wore answered with in a day. Over all difficultie level 1 being plug and play and 10 being i lit my truck on fire to feel the satisfaction of not having to keep trying to complete the job, i would say a 6. Some of the bolts wore horrible to get to, and the hangers on the exhaust had to be heated and bent in order to fit properly.
Bought the full delete bundle, amazing quality and great tunes. Customer Service was great when needing help. Fitment was great and drive ability with the DSP5 was great until I blew my turbo *MY FAULT*, would recommend this company for anyone.
I have installed a full delete system for my LMM and it was super easy to install, I went with a 4 inch and all parts came in perfect just as described with no issues. Looks and sounds amazing
Thank you to the diesel dudes team!
After buying my first diesel truck, I quickly realized I didn’t know nearly as much as I should have. Like many others, I ended up spending far too much money on repairs just to keep the truck stock.
The final straw came after replacing the EGR cooler. While towing my trailer, I broke down on the side of the road and found myself stranded, waiting for a tow truck. Frustrated and fed up, I started searching for delete kits right there from the shoulder of the highway.
Thankfully, TheDieselDudes showed up in my search, backed by outstanding reviews. I was so impressed that I literally ordered the kit while parked on the on-ramp, waiting for the tow truck to arrive.
A few weeks later, with the help of some knowledgeable friends, I had everything installed and was back on the road. The difference was incredible, more power, a better sound, improved reliability, and a much happier owner behind the wheel.
If you're considering purchasing anything from TheDieselDudes, don’t hesitate. Their products are excellent, and their customer support is second to none. They’ll work with you every step of the way to ensure you’re completely satisfied with your purchase.
I purchased this full delete bundle with a 5” exhaust and 7” tip and installed it over the weekend. Took a little bit of time, but was definitely worth it! This really woke my truck up and I love it! I highly recommend this for every diesel owner!

The system seems to work well. When I do have a question. When I put it it in position 3 or higher and I get on it it pops up messenger and other message or saying "reduced power required." What causes this?

This company is 100% customer service driven, and that is what I look for in a company to buy from. Their shipping was fast, their responses were super fast, and their knowledge was supreme!!! When I need more truck parts, this is where I will come to buy from!!!
Worth every dollar
All parts fit as intended. Install was simple with the instructions provided. Overall would definitely recommend.
Fast shipping, worth the money
Wow, the fastest shipping 🚢 you can ever ask for, I got and had to stare at it until I had the time to install everything. Then WOW she come alive runs so much better than it ever did.i do have to finish the egr but other than that it changed my truck to a new toy with an attitude. I was a little worried beforehand but I shouldn't have ever thought twice because The Diesel Dudes did there part just as they said. I received everything they said from the 1st email responding to my order and things went so smoothly I didn't even have to open a support ticket things went so well just follow the instructions and im not the smartest person but i followed the instructions to a tee and went perfectly i would buy another one if I ever needed to. A big Thanks to the Diesel Dudes your awesome.

Thanks Diesel Dudes, my dp filter was clogged according to the dealership,that was going to a 5500 dollar bill. my thruck was in limp mode and wouldn't do much. I ordered the 4" 2007.5 LMM
straight pipe exhaust, with egr delete and e f i live tuner to get my truck back on the road. I haven't done the erg yet, haven't had extra time, the 4" straight pipe exhaust is on and the truck is tuned with the 5 position switch running and sounding great!! Ordering it was easy, the person I talked was knowledgeable and nice. Customer Support was quick to get back to me when I had an issue.
Thanks again Diesel Dudes!!!
Ordering my delete bundle was easy. Had a little hiccup at first didn’t receive the box file to download but as soon as they received my support ticket the issue was taken care of. The instructions on my tune was great. The soft switch install instructions are a little different than what’s on my truck so I haven’t gotten to that yet. I am waiting on my EGR delete to do that and a new 3” down pipe at the same time. But I love the way the exhaust was easy to install and the 5” was definitely the way to go. My truck runs so much better and the sounds amazing. Thanks Diesel Dudes. I appreciate it. One thing I don’t like is I don’t know which tune does which. Nothing on that
It would be nice if the efi live were already down liaded
Exhaust hangers were not quite right, but modified a couple of them to make them work.
Tune seemed to work well!
Haven’t tackled the EGR delete yet.
Over all I am satisfied so far.
Had a little problem and these guys were quick to fix it 👍
The auto call you have sent I believe has no tunes on it.
I go to load the tunes and all it says is parent folder and will not allow me to go any farther
Stephanie, it seems like you left us a 5 star review but are having issues with your order, i assume you meant to rate us lower...
But please open a support ticket and our tech team can help you navigate your EFI live device, otherwise please refer to the instructions emailed to you. If you were missing a tune file, we can send you another one but we need you to reach out to the support team first!
Great to deal with
Great product and was very helpful with my installation. Thank you!
The kit came exactly as described and was very easy to install. I did it all myself. Make your truck move and last longer!!! if you’re thinking about doing it, go ahead and do it it’s worth it.
Will the complete kit allow me to remove the egr cooler as well? What is the additional freight to Alaska for a 2008 chevy duramax complete kit?
Depending on what you are purchasing, it could vary from 199$-299$ in shipping
Do I need tcm tuning if I do full delete bundle on my LMM duramax?
no not typically required unless you are planning on using heavier horse power tunes.
Does the duramax kit remove the dpf and how do I know what size exhaust. I have seen kits that are upright and down pipes for both sides . Do I need that as well?
Thanks
All of our 2007 and newer bundles include pipes to delete the DPF, and the tunes disable the DPF in the ECM.
Factory size exhaust is 4". We offer 5" exhaust as some people like the deeper, diesel rumble and to be a little louder. Both pipes will fit your truck without any need for cutting, welding, or any sort of adapter.
Uppipes and downpipes are not required to do the delete, but they are definitely beneficial for installing the delete kit and long term engine reliability. For the LMM only the uppipe is available from us.
Are Tunes safe and reliable? How much mpg could I gain with the tunes?
Hey man, I like to think our tunes are safe and reliable. We at least stand behind them to make sure you have a tune that keeps your truck on the road. We see a 3-5MPG increase with the kits
Do I have to replace the whole exhaust on a 2010 6.6 duramax to do a complete delete?
Hey man, that is correct. It is a ease of installation desicion. We make these kits so that anyone with basic tools could install it and to do so it is MUCH easier to just remove and replace the entire exhaust
