Diesel Insights: Inspecting A 600+HP Cummins EGR! 

As a diesel guy who lives in an emissions compliant area, you guys are awesome. One of the things that quickly started turning me off to diesel was the responses to questions online about modifications without deleting. Every forum is the same. Question-have a problem/I want to upgrade. Response-delete. But I live in an emissions required area Response-move It gets depressing seeing people so short sighted. I’m not saying the emissions crap is good, but it’s required. And I like where I live. You guys offer the best stuff for us who don’t have the luxury of deleting. And considering how emissions have been getting stricter, your work will be much more widespread.

Awesome Nick , you guys are are great. Chris is who has always helped me . He does a great job and always easy to talk you..

Just an FYI here Nick , California Trucks ( Duramax powered at least ) got EGR systems as early as 2002 ( I have an LB-7 of that year) in my truck & it has one . Thankfully it’s NOT given me any issues in my almost 22 years of ownership so far . I DID have to replace the vacuum pump 2 years ago that has a connection hose to the EGR diaphragm that controls it’s open & closed cycles , but other than a check engine light that came on when vacuum signal was lost (. Thank God for Internet forums ) I was able to figure it all out & replaced pump. Thanks for all you post buddy . I’m curious to see what my intake looks like inside some day , but until I need to tear into my engine for some reason I’m leaving well enough alone !! 🤞😎👍

Good work i have learn a lot from your channel

Excellent video! Thank you!

love you guy can't wait till i get my dt750 trans and the stealth 64

It's nice to see how it works, if I still had mine on there lol

So we are trying to reduce nox because it make bad ozone in a troposphere and ozone is heavier then air so it won't go into the stratosphere, right? But CFCs are several times heavier then air and the EPA says it goes to the stratosphere because of winds and jet streams... idk I'm not saying they are wrong but I have questions I guess no one else has asked.

Ive noticed the filters and catalyst evolving every couple of years but it's crazy they've come this far in 2020! How low is the NOx threshold on the automotive SCR system? Its unbelievable they can handle that much CFM's.

Nice Sonic 👍

That's comforting to see the egr system that clean running that power. With the twin turbo setup does dpf soot loading stay same or more or even less? Or since it's tuned are you able to passive regen more?

What other supporting mods are done to this truck to make it run as efficiently as possible?

How do EGR valves look after a truck has had it turned off/closed for over 50k miles or so?.

Just pulled a egr and intake manifold off of a 2016 Powerstroke, all stock with 50k on it for maintenance. Completely sorted up with a 1/4” off soot inside the intake plenums.... absolutely worst thing a diesel could have on it. Not gonna change my mind since my 5.9 grid heater is completely clean and looks almost new with 260k on it. Truck runs just as clean as a new truck unless I rip on it. Also DEF is processed urea and creates extremely toxic emissions when burned much more toxic than NOX emissions and that’s been scientifically proven.... ya know when the vehicle goes into regen. Not to mention the added fuel consumption that these emission create by nurturing these trucks. It’s truly a shame what’s happening to diesels, they used to be reliable longevity fuel efficient machines... EPA gets their claws in the mix and now they are far from reliable and extremely inefficient. 6 MPG towing in stock form!?! Really. No thanks I’ll keep my 5.9 without any of that stuff that runs clean, reliable, fuel efficient, not being fed it’s own SH$T and will actually last.

Are you sure you don’t work for the EPA haha. Nah great video very good explication of the system. Thank you

This is good to see. I am personally someone who will keep the emissions systems on my truck if I go to buy one. It's illegal to remove them, which means any LEO could pull me over and flag me for it at any time if they really wanted to. It may not happen often, but it can. However I think I will just go for an older model truck with just an EGR and get BulletProofDiesel parts on it (when it comes to emissions system equipped trucks).

Good afternoon. I have RAM Cummins 2019. Tell me the best solution so that I can programmatically remove ecology (EGR, DPF, DEF), add horses, prescribe wheels, read/delete errors. Thank you.

So what are your thoughts on a non def 2007.5, 6.7? Reliable like a 15 and newer?

So what’s the average percentage of fresh air to exhaust gas going into my engine?

I agree that all the new generation EGR systems are better quality and maybe require less maintenance. I do wish He had of finished the video with a inspection of the intake valves and intake plenum! That is where the real concern is.

When I pull the egr off my truck last summer( I’m in Canada) my egr valves, coolers and piping looked like that also with 400t km on it. But the Y bridge and intake ports going into the head is where it was built up and the valve ports were almost clogged right off. Not sure how it could make any power at all.

I currently have a 2016 ram 2500 cummins that I deleted. I have been looking at putting all the stock parts back on and using an emissions compliant tune. Do you offer tuning for the EZ LYNK with SOTF?

I want to see the grid heater.

I would like to see how stopped up the heater grid is.

I'm very interested in running your tuning setup on my 80k mile 2013 2500 68RFE truck, are you seeing any issues with DPF failures or other issues when you tune a higher mileage truck? Thanks for the video on the EGR system, I learned a lot from it!

Do you often see failures on LBZ Duramax EGR systems? If so, are there any upgrades to EGR components to make this system more robust?

Any oil Analysis? Is there any harm done long term by having emissions intact?

Y'all are coming out with Stealth 64 for 4th gen cummins?

Should I take off and clean the EGR valve once and while? If so how often? Thanks

I have a 2007.5 Cummins and I am interested in doing compounds?

@Duramaxtuner will their be a video for GM?

Let’s revisit that truck now. It’s been 2 years since this video.

Are all these miles with the stock trans but with your tcm tuning??

I have a 2018 ram 6.7l . How much does this setup cost?

EGR failures are common on the Ecodiesel.

I have an LLY. '04 1/2. What should I be worried about with the EGR system on this truck? Anything in particular I should look for?

What is the tuning power level differences between a deleted truck and a truck with emissions intact ?

Whose compound turbo setup?

With 600+ HP what kinda fuel mileage y'all getting?

The best EGR on a diesel engine is one that has been removed. Nothing good can come of a diesel engine via EGR. THE END.

Sure no EGR failures but DEF failures all the time now. It's all has to be taken off the truck. They run way better.

You need to delete the egr

so.....the president of duramaxtuner drives a WHAT? tsk tsk tsk... just messing with you.

The engine would be much more reliable without dumping exhaust gas into it, as it add more wear to the valves, piston, cylinders plus oil dilution & air dilution in the combustion chamber.. Then again, most every gearhead knows that.
