Has anyone with an 06 disconnected the egr valve? What have the results been? I have read a little bit on here about it and am considering doing it myself. I am not having any problems with mine, just looking for info.

 

I have an 04 6.0L with the EGR unplugged. It makes a difference in turbo spool up time. Also, if your towing heavy loads you may melt the hose that is connected to the EGR cooler. I recommend to disconnect the EGR but there has been many discussions on the topic.

 

I have been a big advocate of disabling the EGR Valve on '03, '04, and some '05 model years....and still am. I do not, however, recommend it on '06 / '07 MY. There have been many improvements to the EGR Valve strategy so I wouldn't do it until the little bugger mandates it.

The EGR Valve longevity can be enhanced by using high cetane fuel and/or using a quality fuel additive. The advent of USLD will also help the EGR Valve live longer.

 

I disconnected mine a couple weeks ago. The first thing you will notice is the check engine light will come on after you have driven the truck and shut it down. The light will come on the next time you start the truck. I do not think there is a way to turn the light off, someone else on here can answer that for you I'm sure. I do however believe the turbo does spool up a little quicker. Boost might not run as high as with the egr plugged in, probably because the turbo doesn't have to work as hard???? Mileage is a ? also. Good Luck in whatever you decided.

 

When I disconnected my EGR valve, I didn have a check light come on.

 

By what I've read on other threads on the disconnecting of the EGR the light doesn't come on until the 06 model. I tried this past weekend because it wasn't supposed to but it did so I hooked it back up. it took probably 3 start/run/stop cycles before I got the light to stay out. I've got an 06 6.0 250 Lariat

 

Ok, well in that case your better off getting a Xcal tuner so you can turn off the EGR function altogether. No light and no trouble at the dealership. Unless you can live with the engine light. But what has been said here, there has been improvements with the EGR in the newer 06 - 07 trucks. Maybe someone with the same year truck can help you out.

 

I have disconnected mine on my '04 with great results...slightly better fuel mileage and much better turbo spool time. But to clarify the check engine light, I do not believe it has to do with model year. The light will come on if the truck is equipped with the California emissions package, all other trucks will throw 2 codes but no engine light will come on.

 

My 07 got the Chk, Engine after first run. At 400 miles I just plugged it back in. Didn't really notice anything anyway.

 

Had some problems with my 04 f350, took it to dealership. Could not get it to spool up at all, black smoke, barely got it there.... Was not giving me any codes or check engine lights at all. They replaced the EGR removed and cleaned the Turbo. Its runs very good now. But now after you turn the truck off, the injectors sound like they are still firing for about 15-30 secs. Any one know why?

 

iv got a 06 250 and i unpluged it the light came on but however, my friend has a 05 350 and his light never came on ..... i didnt notice a differance really.... your choice... but make sure you plug it back in b4 warr. work ... that will help(take it from me)

 

yeah i have a buddy that had problems with his truck stayin runnin took it to the dealer at least 3 times... thats what they did to it to ... it cycles the injectors for some odd reason too .... but i dotn not knwo y it does

 

The new Ford Flash update cycles the injectors for 30 seconds after shutdown to clear oil out of em for cold weather starting.. Suppose to make the injectors last longer..


So does anyone recommend I yank the EGR on my 04? If so where is the booger and what am I disconnecting?

 

I ran mine disconnected and plugged into a spare for 20000 miles. I don't have any scientific way of proving anything, but it seemed to run much better at first and then grew worse over time untill I pulled the egr and cleaned it as well as the IAT (intake air temp sensor) and my truck seems to be happier back factory now. That was 10000 miles ago and I think I'll just pull mine and clean it occasionally. I think the computer even on the 03 like mine is smart enough to figure out something in the pressures is not right and try to compensate for it after a while.

Unplugged the EGR on my '06, with the triple pup tuner, no check engine light.
