As far as the throttle plate, do you think it gives any power gains...essentially is it worth it? Are there any effects of the throttle plate being removed if you were to take it back to the dealer and had to plug the egr valve back in? Also, did you guys do anything to weather proof the egr plug or connector (not that much water should get up in there)...just a thought.
I did unplug my egr, and the lie o meter was giving me 1.8mpg better on a drive that I have never gotten better than 17mpg on I got 18.8, so glad I finally got sucked in to the forums and started reading. I signed up a while back, but have been really busy with my senior project... Now that I have just graduated with my engineering degree, it's time to start playing with the truck (I have some spare time) and this site is amazing for information.

The EGR system on a 6.0L diesel has nothing to do with emissions. In a gasoline engine, it prevents the formation of NOx by diluting the air/fuel mixture--thereby making it richer, which burns cooler--to prevent NOx formation. On a 6.0L diesel, the EGR is there strictly for noise control, as set by the California Air Board. You'll notice if you stand in front of a running 7.3L PSD, you have to shout to be heard. Not true with the 6.0L, you can hold a normal conversation.

What in the heck are you talking about? Page 600 and something and you come up with this little gem.
Do you even know what EGR means? Actually, do you even know what a 7.3 or a 6.0 is?
Seriously, you can't be that ignorant.
But then again, maybe you really are......
BTW - I'd challenge you to have a conversation
within 20ft of my 6.0 first thing in the morning and be heard. My poor neighbours.

OK, I'll bite, although I know I'm wasting my time.
Cummins, Detroit, International and almost every other diesel manufacturer, (except for Catapillar) and a a few billion dollars in R&D dollars disagree with you.
You obviously have never heard of tier 1, 2 3, etc emission regulations.
OK, I'm done

Ok guys, this is my first post, I found this forum doing a "disconnect egr valve" web search and this site looks quite addictive. I haven't read through all of the threads on this subject but in the few pages that I have read I'm sold on disconnecting my EGRV. The 4th one went in last night at the dealer and I'm getting tired of the $100 deduct, the last one went in Sept. last year. I haven't set up my personal stuff but my truck is an early 04 (Late 03 build) F250 FX4 and I have 48K miles on it. As far as noise I don't care, nothing can be as loud as my 2000 7.3 and that didn't bother me, as a matter of fact I wish I still had that truck. I'll be interested to see if I get a check engine light. I just wanted to say thanks for all the info that I found here, if it wasn't for the UFC fight and superbowl this weekend I would probably spend a bunch of time here

Or better yet, call me, I'll tell you how.

Here is a link you might want to take a look at. This is straight from Ford's own "coffee table" service manual.

The picture I included is pulled straight from the Ford Technical Service Manual.
So let me get this straight...You are telling me that you know more about how these engines operate than Ford, International, Ford's own techs and all of us who spend a good portion of our work and free time studying, working on, and modifying these engines?
I have only one question, my friend...just who do you think you are?

EGR's new meaning...
Wow, he's made two posts, and after almost 700 posts, his 2 posts have completely changed the meaning of EGR. Since Exhaust Gas Recirculation is no longer effective, it has now been changed to Engine Growl Reduction. Thank you for your infinite wisdom in pointing it out to the thousands of us who were lost.

Today I installed a dummy egr valve on my 2005 with califonia emissions. I purchased a new one from one of our site sponsers. The price was resonable and if it doesn't work I will have a spare. So far so good no check engine light and boost is back to normal. Hope it stays that way. I'll give it a couple of weeks and see what happens.

Free power upgrade!
Even I know when to keep my mouth shut! What an imbecile. (I write that with the deepest and most disconcerting disesteem) Buddy, just read and learn.
AND DON'T BE
Anywho... I unplugged my EGR. I gotta' tell ya'... I'm thinking about not buying a programmer anymore because the truck now has SO much better throttle response.
My 16 yr/old son noticed it as soon as he drove it, and I didn't tell him a thing about doing it. The 16 yr/old foot knows!

I have read most of the posts on the egr disconnect and I was wondering if the egr only opens when the exhaust back pressure is greater than the intake pressure why one wouldn't modify the exhaust pressure sensor so the pcm never sees this condition. Maybe a resistor inline so the pcm still sees some back pressure but not enough to tell the egr to open.This is my first post, just got my 6.0 back from the shop having a turbo scrape done and sticky egr replaced.

i've read some of the pages here on this thread, but my main question is, if i have my 2006 6.0, and aren't experienecing any problems at all, is it still smart to disconnect it? i don't have a tuner and really not sure if it's working properly why so many guys are doing this. i'm being serious here and not trying to degrade anything that's been said in this thread, just curious is all. if someone is having trouble with their earlier built trucks and unplugging it seems to cure the problem, than i can see that but not sure if it's something i should do to my truck or not. when it's running great.
thanks guy.
