EGR Delete/Turned Off

**TexRM** · 02-12-2021

So are y’all saying you can turn off the EGR with a tune and that’s it.

Everything else will run as normal?

Yes, but you will need to remove the exhaust (DPF & SCR).

Completely agree to the above said.

My two cents to go along with it was when i had my 2012 i deleted it at 7500 miles and once i took of the intake and everything you should have seen the amount of soot that had already built up inside of it!!! The not so pleasant way to describe the EGR is basically this...

Take burping for instance. your engine exhaust is you burping. In order to try and make it cleaner it takes a portion of the exhaust gases the engine generates and runs it back through the intake in hopes of the second round burning more off then the first round did. So think of a tube coming from your mouth to your nose and a little 3 way valve. one valve going to atmosphere the other going back into your nose to be recirculated. 3 way valve being the EGR Valve. haha i apologize if it is somewhat disgusting. But why leave all that in place when it can be free and clear! Even if the tuner turns it off it will still be better overall in my opinion to take everything off. Also i would recommend keeping all of your extra parts just in case. Unless you are hurting for cash then you can sell and make a pretty penny.

Let me know if i explained it correctly but thats how i understand it!!!

i'll probably do the same... leave it and just turn it off. I can turn a wrench, but it would save me effort/time to put the truck back to stock in case the tuning doesn't work and I own the truck of Satan. been reading too many stories of folks that are deleting/tuning... worries me.

I know I am late to the party, but, I was in the same boat and after running the MM3 with the egr hardware still attached for a few months, I finally decided to remove all the hardware. The first thing I was astounded by was the amount of soot in the intake from the egr. After removing the hardware and throttle valve body, I am amazed at how quite my engine has got. On the road, all I can hear is a nice quite exhaust and I can't hear the engine at all. If you are going to keep your truck for awhile, then get rid of the egr.

Ray's advice is spot on.

If you plan on eventually trading in the truck, or aren't likely to keep it more than a few years, just leave the EGR hardware in place.

I'd add that if you live in an area prone to visual emissions inspections, leave it in place.

If you're set on removing it, in my experience the eBay block off plates work just fine.

You can spend more for a name brand kit, but you don't need to in order to get the job done.

The most common failure point is the o-ring in the coolant riser adapter, and if you look around the forums and FB pages long enough you'll see them fail on high dollar kits as well as the cheap kits.

I can't beat 78$.

I was going to leave it all intact, but I don't plan on getting rid of my truck so I'm just gonna do the EGR delete.

Do those O-rings fail often?

Like should I have extra's hanging around just in case?

I think this is the Oring that fails in the kits from my research, folks recommend getting this one from the OEM

OK, now after seeing this thread I have been thinking.

My original (and still) plan is to not remove the EGR hardware.

I've seen in lots of places, and videos that it would be very hard to put back on.

So my question is had anybody ever put their EGR hardware back on?

Was it that hard?
