Just bought an 09 with the 6.7. I want to try and avoid the turbo, DPF full, and the Clogged EGR problems.
The first thing I want to do is unplug the EGR. I have read a few post's and it seems to work with no problems. Can any one give me a reason why I should not unplug?

 

The only reason not to unplug is the guilt you'll have to live with from cheating the oil companys out of a few gallons.

 

I would run at least three tanks of fuel through it, so that you at least have a bench mark of your performance and mileage before messing with stuff. Don't lug it around town or on the highway either.

 

Learn how to drive a diesel engined truck, keeping the engine in its operating range, and you should not have to do anything.

 

Unpluged mine before i left the dealers lot!!! ................JUST DO IT............

 

I slightly agree with this guy, although not always practical. You cant always have a trailer hooked up for every mile the truck gets on it, or always me cruising on the interstate. I would just drive the truck for the purpose you bought it for, whether it be towing, highway driving, or just that you love dodge diesels, and see how it goes. If it goes into the dealer with emisson related concern and you then feel justified by whatever right to unplug something and mess with the original configuration, then do it. I would just definatly wait until you have a problem before you go and create another problem.

Just my 2 cents though! Hope you enjoy your truck and tell us how it all goes!

 

First, I have been driving diesel powered trucks of various sizes for more then 20 years. Some good, some bad, but none of them ever came with so much emissions equipment (Crap) as my new 09.
I have read many post's of guys who have had problems with their 6.7, and I would like to avoid those problems.
I can not possibly run this truck hard enough on a daily basis to prevent build up of carbon. I bought this truck to haul 28' travel trailer on the weekend during the warmer months. The rest of the time, it has to go about 1 mile to work, pick up the kids from day care, and occasionally haul groceries. I would love to have a second vehicle for this, but it is not in the cards at this point.
So, my thoughts are, if I reduce the soot intake into the engine, this should help reduce the carbon loading and increase the fuel mileage. Can't see anything wrong with that, can you.....

 

The EGR is the killer of the modern diesel engine. We have come a long way from burning coal dust to injected fuel and now the engine has to deal with coking of the intake plenum and cylinders with dark cool soot. Hense the change in oil grades to hold all this residual soot, usually reserved to those with 50psi boost and hard fuel.

Disabling the EGR IMHO can only make the engine perform better. If you have ever seen a 6.7 with the DPF delete and still has the EGR idle, you would be sick to see the soot that comes out of the pipe. Just idling I was amazed at the dark cloud that forms at the tail pipe. Just because the tail pipe is clean now doesn't show you the story of whats happening inside.

For me, I would take insult to comments on "how to drive a diesel". We should not be subject to that kind of jabbing.. Information only would be appreciated.

This is an automotive diesel engine and should be able to take the day to day rituals of use no matter what we do with it. I don't tow with mine every day, but it is used every day for travel to site. Mechanical trucks carry 15,000# and have to idle all day to run PTO equipment for their job.. How are they supposed to deal with this problem???

 

Lil Dog,
I chose to take the high road on the comment about learning how to drive a diesel. I do not know if he meant it the way it sounded so I let it go.... If he did, I'd like to give him one of these:

Congrats on the new truck! I've been suffering dieselitis since my 100% trouble free, flash free, never seen the service dept Hemi powered HD Ram reached 100k miles. I didn't take the "how to drive a diesel" comment as negative. They need to be driven in a more spirited way than most think of when it comes to diesels. We tend to think of lumbering ships and trains and other big diesels. Not the same animals at all. Then again, petering around town like a funeral procession will clog up the EGR on a gas engine too. My dad did it to his Honda Accord. So, when the day comes that I trade my loyal Hemi for my 5th Cummins Ram, I'll be leaving everything in it's stock form as I've done with all my trucks. I will refrain from fuel or oil additives regardless the temptation of the packaging. I will use OEM or equivalent approved filters and fluids. I will use the proper builder approved oil even if it doesn't come with a sticker. I won't let it idle excessively and I'll take it out with the 5th wheel once a month and, I'll drive it around town on my work route like I have a pulse. Amen.

The main reason I don't plan on unplugging anything is that it should work as intended as it is. Mercedes uses the BlueTec after treatment in their diesel cars and I can't even find any complaints about it. Ours should be designed to work every bit as well. Won't be the first time my overly positive outlook as been squashed!
Wanna have a nightmare tonight? Look at this scary exhaust choking BlueTec picture!

Mine has been unplugged for 3000 miles plus , all I've seen is 2 to 3 mpg improvement.

 

I have had my 08 for about 6 months and have about 18000 miles on it and have had no problems with the emissions controls I do pull a 48 foot enclosed trailer or a 30 foot enclosed most of the time.
But almost every time I get back from a trip and have gotten 9-10 miles to the gallon I think about taking it all off

 

Oh, thats all?? Geeze...

 

x2. 9 MPG towing a 21" toy hauler at 65 MPH sucks!!!
