Dude, you’ve got a lot of faith in that plastic ramp.

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.

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

Just found you on RU-vid not long ago. Got 2015 srw 3500 lml duramax. You good sir have some of the best videos I can understand. Getting ready to do some work on it from this video, and I feel like I should send you a paycheck check for the free info. Keep it up bud its greatly appreciated.

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.

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

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

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

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.

Great video. When done do you plug the first 3 plugs back in when done?

If I have some pre existing codes would I need to fix those before adding the tune? Asking for myself

What if you’re already in limp mode before you start the process?

They make hanger pliars that make taking the exhaust off the black rubber super easy

I just bought a 2013gmc its already been deleted can i add a tuner now or would i have to find out what tune they installed in it first

so your saying that the truck will still run without the throttlebody plugged in ?

What state is it located in bro ?

Why unplug throttle valve?

Can you please explain what and why you disconnected those plugs at the beginning?

Hey brother I've watched several of your videos. Awesome job. I want to ask you how long it how many hours do you charge for to do the full delete? EGR and Def

Hey buddy i have a question is important unplug that wires you unplug in the engine

The first one is the nox sensor on the turbo

Nice job wish I saw this before I did mine! How about a video on egr delete and up pipe.

What about the nox sensor directly after turbo outlet

Awesome video, great detail!

Great work you got a new fan!

After the exhaust sid you have to do computer stuff

Hey buddy when you finish with the exhaust you plug the wires back or no

I have a 2016 hd2500 6.6. I would like to do the same thing with my truck. To many problems with the def system. Is the part number you installed on the truck the same for my truck? I searched for the on 664nm and can’t find it. No listing anywhere in my searches

hey there , i just purchased my first lml duramax 2012 gmc , trucks got 306,000 kms , all stock , would you recommend a full delete ?? and straight pipe it perhaps ?

I have a 2021 GMC with the 3.0L Duramax and I have been trying to find everything that I need to make my truck better but have not been able to find anything. Could you guys help me out

Do you leave the 3 plugs under engine unplugged?

thank you so much for the detailed video. Helped me breeze through this removal.

I did this today and when i started my truck up def fluid started flowing is that normal?

I'm new to diesels. What happens if you tune the truck for a dpf delete but don't actually remove the factory exhaust?

Will leaving the egr and coolers on be ok? I have heard different opinions and I am considering deleting but don't want to have to remove egr if it will be ok.

Im thinking of buying the 2021 Duramax 3.L can you delete the DEF on the new trucks after the warranty is out ? And what would be the cost estimate?

Just subbed...Thanks for your excellent video... I have 2011 Duramax and after watching your video feel that this delete is something I can tackle. Your tips and attention to detail are awesome. I love the Flo-Pro product and would go with the SS864 but I live in the USA and I am not sure where to get it? Also I’m torn between the EZLynk and the H&S Mini Maxx? Any insights would be appreciated! Sorry about the length of this post but I’d really love to pick your brain about this!!

How do I reset to exhaust light if I put program on truck before I took off exhaust with a efi live

Do you do this professionally for private parties? I live in a state that has no requirement for emissions control testing.

On 2016 3500 gmc if my truck has went into limp mode because of fail def pump will the efi live tune for def delete clear that or do i need to fix the limp mode first.

*Epa has entered the chat*

If the truck is already in limp mode and decide to do delete will this get rid of limp mode? Or does efl live or any programer erase the limp mode

I just picked up a 15.5 lml and I am having trouble finding a tune to delete the truck any help?

Hey I recently purchased a 2012 lml that someone did this to but just welded in a straight pipe in its place and reflashed the ecm. Just curious where I should go from here I don’t have the stock tune or def and not sure if I do the full egr next or what looking for suggestions or options. Not really knowing what’s the next step.

great video ... whats the best set up for 2015 silverado 3500hd duramax ? i want to delete all the DEF crap. also if its deleted can i replace the system if i sell it? thanks again

My truck is in limp mode already. Do I have to have it repaired before I delete it? It has exhaust fluid poor quality codes due to a plugged DEF injector

It’s supposed to distribute the carbon build up evenly throughout the filter, if it does or not is anybody’s guess

What does it cost to do this?

Great Video. Where can I get the FloPro exhaust system? Direct from FloPro says no shipping to the US.

Cool video man! What website did you use to download your efi live tunes for the last video you made with that white 2016 Cummins?

Yo i got everything but the delete part with the programing and stuff idk how to do that

I just picked up a 2011 chevy 3500 reg cab I'm in love this is on my list subed

I plan on setting up my own hot shot business. Is deleting a LML a bad idea?

hope someone can answer this even tho its an old video. Would i be able to delete my lml and keep the stock exhaust to make it look as normal as possible and avoid any kind of trouble

I have a truck diesel I want to do it like that please I need more information

Does the check engine light stay on?

You’re brave posting this stuff

Im trying to get the dpf deleted i have efi live it’s not legal here in the US were i am but im using this vehicle for track and off-road use only, on another note im looking on efi live software but the software don’t have the option at all. Any tips or helo would be greatly appreciate it

Do you recommend a muffler with the 5" pipe kit?

Any recommendations for mechanics in Huntsville, AL that can do this?

Hello I'm thinking about doing this to my 2013 duramax. What do I need ?

About how long did it take you to delete the truck ?

Is this the same process for a 2015 Denali ?

Would this be pretty similar to the different body style 2016 LML?

Do you have to tune it if your only doing a straight pipe

Exelent video bro!! Question so with efilive tuner thats all i need to do to delete? Im new to the duramax life Im subscribed!

I have a 2015 gmc denali 2500 6.6l I would like to do the same

What’s the purpose of disconnecting the plugs in the engine bay post-tune?

Is this procedure the same with a 2017?

Do you keep those 3 plugs that you unplugged under the hood disconnected?

cant do it in utah if you want to register it here

Where can I get the tuner

Where can you get one nowadays?

Is this pretty much same process for a 2015?

Great video 👍

Hi man! I enjoy your videos! I have a question if you could answer for me.. I currently have an h&s tune on a 2013 lml and just curious if low boost fueling is effected when removing speed limiter? I had it removed with low boost set to 4.. throttle was very responsive. Later retuned to keep speed limiter on so I would have cruise however now throttle response feels sluggish. If you can't answer no problem! Thanks for the video though! Very infprmative👍

Hey brother, you have any info on a 2017 L5P duramax, and how to tune them?

Hey how do you get tunes for your ez link tuners.

Will this exhaust kit fit a 2013 LML regular cab long box.

Is that double-walled exhaust on the factory pipes, or is that just the slip fittings over lapping?

Hey bro couple quick questions for ya, those three plugs you unplug in beginning of this video , do you leave those disconnected permanently, and if you do plug all three bak in will it cause any problems like limp mode or any other issues ? Thnks appreciate it

I had my mechanic do my egr delete and now I have a real loud whistling sound and don't know what to check I have a 2011 gmc lml duramax any idea

Great vid....2 questions...my truck is in limp mode already, will the tune and delete clear that out. Also will the three things under the hood remain unplugged after modifications?

Question bro, about how much does it cost to have this all done? Tuner, straight pipe, def delete and labor?

Do I need to unplug the def tank wires if I’m leaving it under the truck? Or just do everything else and not touch anything to do with the def tank?

QUESTION: Diesel Particle Filter Full Light Engine Power Reduced Light Check Engine Light 2016 LML Duramax 3500 Lights all came on. Drove the truck 60+ miles. DPF, EPR lights are gone but Check Engine Light still on. Is this normal??? How do I get rid of the light? Can I clear it with my Bosch scanner? I want to do a delete but still want to look and sound factory. Any suggestions?

Just did a dpf delete on my 2013 LML duramax with Minimaxx tuner, but for some reason the truck randomly loses power. No CEL or and codes do you know what could possibly cause this issue?

Do you plug in the 3 engine harnesses back in when done?

Installation is pretty much straight forward

Do you recommend the FLOPRO exhaust over other brands? Getting 5" (no muffler) for my 2015 LML soon. Thanks!

Can you delete without removing Def tank and tube? How to tell if a 2014 duramax has been deleted? Emissions test failed stating cat converter fail.

I'm having a hard time finding the flopro exhaust kits online. Downpipe-Back is what I need just like your install here. Where do you buy? Thanks in advance.

Thanks for the video! I am getting the DEF poor quality warning on my Duramax 2013 and was wondering if, for now I can just unplug the sensors and do a DEF delete reprogram and leave everything else installed?

What dose it mean when white smoke comes out when you just did a deff delete

What are you running for a tuner do delete?

Love it❤

Great video: question for you, is unplugging the EGR good enough? Or should you remove that also? I use my Duramax as a work truck

Is that what you do to roll coal
