Hey brother. Thank you SO MUCH for EVERYTHING!!! You’re video is literally the reason I was able to delete my 15 LML. QUESTION!!!???🚨🚨🚨🚨🚨 Do I RECONNECT the 3 clips on the top of video?!?! The FIRST thing you showed us throttle body one and 2 right after…. Or, zip tie em outta the way forever?

[@rabbitholeresident6490]

Got a 2011 lml and run efi live. Runs great and no problems whatsoever. The sound of the straight pipe never gets old.

[@armandocastaneda5898]

straight pipe?

[@akula682]

@@armandocastaneda5898 Straight Pipe means No exhaust, No catalytic converter, No DEF injection. just a free flowing pipe from the down pipe (engine) back to the end of the pipe.

[@jaasonbee]

Thank you for the video! One tip for anyone who doesn’t want to remove the def tank is to make sure you unplug the big harness or it will continue to spout def fluid onto the ground…the mini maxx tune worked great

[@Duramaxmanny]

Did the mini max tune need to be programmed by a shop??

@@darkirondiesel a question I have a GMC DURAMAX 2017 we fix the truck for a accident. After fixing it, the screen tells me that the exaust fluid , I have a few miles to run. many people say I need to change everything and delete . but my question is can the computer be reprogrammed? Because the accident was not a big deal, that appeared to me because in the shop where they fixed it, maybe they moved it without adding liquid fluid I hope u can help me thanks a lot 👍

[@hyde4787]

Would love to see you do a CP3 install on the LML. All your content has been a great help. This was probably the best DEF one i have seen.

[@darkirondiesel]

If I do a cp3 conversion I’ll film it!

[@TheMatthewDMerrill]

I just finished deleting mine and it works much better, I will update with mpg when I have that info. I only deleted the dpf and got my tune from tunerdepot as they were the cheapest. I used the efilive autocal v3. It cost me less than $1000 to do as well, only thing I bought was the tool and a tune. I opened up the dpf and removed it then welded it back closed.

[@aaronbailey9120]

Your video made this so much better! Hands down best video to date! Keep em going man! You're very thorough!!!

So once i tune my truck to run without the emissions do i pull the key out to kill the power before i unplug my egr?

[@waynejohnson3388]

I'll be following this video as I fix my truck.

[@Chevytech1977]

As much as I hate the emissions on gm diesels, this was a very informative video. Kudos for giving that disclaimer at the beginning to cover your butt. If you're in Ontario you can't even sell this vehicle because no licensed Tech with half a brain will risk their license to pass these! The fine for deleted emissions in Canada is around $10000 last I heard. Might be more now.

Excellent video man. I am new to diesels and all I’ve heard is delete delete delete! Now I understand! I’ll definitely do it myself after watching this

[@kphuntingandfishing4337]

How did it go?

[@jimhannis5518]

I love and agree with the comments about your content being thorough and no goofy music and foul language. Hats off to you. I have a question.. Can I do a DPF delete without doing an EGR delete? I plan on doing the DPF delete with The H and S Mini Max. But I do not want to do an EGR delete if I can get away with it.

[@omarmunoz740]

Yea that is exactly what he did

[@Ah01e72]

Followed your video for this, my only issue was the straps for the def tank cover that were high on the body side were torx bolts and stripped both so I guess the tank will be staying up other than that your video helped a ton the downpipe was extremely fun

[@susanstofiel9490]

I have to say, you have the most informative videos I've ever seen on here. You know how to move the camera so we can clearly see too. Thank you. l do have a question that I can seem to find an answer to....I have a 2013 Durmax 2500 HD with the LML motor. I bought it from a used truck dealer about 6 years ago. What I didn't know is the the def system had been deleted until I took it back a month later because of a hose hanging down. They said it was "chipped and deleted" Now, years later, the motor is blown and I am going to be having it replaced with a "drop in" stock motor. I didn't think about that?? What would I need to do? Buy and replace the exhaust system? I don't want to go to the DEF system.

[@darkirondiesel]

Just replace the engine but keep the ecm and exhaust you currently have. Also, you should get the trim codes from the injectors in the new engine and have them programmed in with a scan tool (a normal repair shop should have a scanner capable of doing this)

[@susanstofiel9490]

Thank you! @@darkirondiesel

[@travisneumayer7584]

Not sure where you're located, but would be willing to get my truck to you if you could help. You're clearly the right guy for the job. I've got a 2012 Silverado 2500 HD. Was driving back from a very long trip and just made it back into Minnesota while towing an empty 24' enclosed trailer. Speed was relatively low, about 60MPH and right as I accelerated to pass, there was a loud gunshot sound. The bang sounded like it came from behind the truck but not from a backfire as it never has in the 40,000 miles I've owned it. It was nighttime so I couldn't tell if it was dark or white smoke, but there was a LOT only while using the diesel pedal. DPF message came on about cleaning the tank, so I stopped to fill it, hoping I could just limp home. After filling, engine power reduced message came on and the trucks speed was limited to 39mph by GPS. 40mph per the dic. Took a few miles to reach that speed as well. If I put the pedal down to accelerate the engine would surge down like it was shifting into a lower gear like a exhaust brake, though the exhaust brake was off. If you're willing to lend some advice so I can DIY or if you're willing to physically help, feel free to call or text 6125014095. Really look forward to hearing from you. Codes P2463, P0420, P0299. Thanks to anyone for any educated reply.

[@darkirondiesel]

Hmm that's strange, I don't know what would cause the loud bang sound. The first two codes are emission related, but I believe that third code is turbo related. Super tough to diagnose without actually seeing the truck in person. As for location, I am located up in Saskatchewan Canada, so I doubt you would want to lug it all the way up here haha

Thanks for the video! I have a 2012 GMC duramax and I need to delete it and install a 5” exhaust so this helps a lot! Question is though what tuner and tunes do you recommend?

[@darkirondiesel]

Personally on a duramax I recommend just slapping a single EFI Live tune on. Either a 25 or 45HP level. 25 if you tow heavy lots and 45 if you mainly use it for daily driving unloaded

Im going to do a basic dpf delete as soon as possible. Just worried that the egr is stuck open. It’s running great. A mechanic friend of mine told me that if that valve was suck open it would be running like crap? What would happen if I did the dpf delete and the egr is stuck open?

Any insights would be appreciated! Sorry about the length of this post but I’d really love to pick your brain about this!!

[@darkirondiesel]

Honestly if all you are doing is just a basic delete, a Mini Maxx will be fine. If you are wanting to do some serious engine upgrades you will have to go with custom ezlynk or efi live tunes

[@velvetfog8815]

Dark Iron Diesel Thanks for your reply. That is good to know. I have decided to upgrade to the AirDog 2 4G fuel pump as well. Hopefully the Mini Maxx will still be satisfactory?
