EGR Yes or No
Ok everyone with this wonderful EGR debate.......
I have read many posts on this topic and seen it go back and forth between do it and don't do it............ So what is everyones opinion TODAY from those that have tried it. Also I am talking about the 6.0 motor 2005 or newer.
Don't do it?
Unplug it?
Remove it?
Block it???????
What do you think?????????????

Don't unplug it. You don't "block" the egr you block the egr cooler. If you want to block the egr cooler but not run custom tunes to disable the egr then you will most likely throw a code whether you weld the egr valve shut or not.

I'll go against the grain a little here....and my truck seems to run better with EGR enabled:
If you're running close to stock power, I'd address the source of EGR cooler problems focusing on your cooling system - filter and fluid in good shape. The system seems to handle the cooling needs of stock power OK.
If you're pursuing high power, I think you'll stress the EGR cooler even if in good shape, so go ahead and block the EGR at the up-pipe, and disable EGR via your tuner.
Regarding EGR in general, I'm curious if we're seeing a reduction in EGR valve problems with the rollout of ULSD. In theory, it should be better with respect to the valve itself plugging up.

What are you modding intentions with your truck? If your going to be doing more then a tuner, then you might want to think about blocking then otherwise you will more then likely have problems with it. The other problem with the egr valve is I truly believe that is why we are seeing carbon buildup on turbos, so that's something else that you can have a problem with it, but that is easily prevented though, just an extra nusiance to have to worry about though.

I have heard that disabling the EGR valve w/ just software isn't a sure way to know it's actually closed (I understand gasses can push by the closed valve).

The EGR valve is closed when you shut the truck off. Using a tuner to bypass the PCM operation of the EGR will keep it closed.
I was able to mod my EGR up-pipe and use the SCT to prevent throwing codes. BY far the turbo spools easier and I'm happy, the truck pulls like a mule, runs hard and fast, and I haven't lost ANY mpg's over the whole deal. If you are loooking to prevent EGR cooler problems you need to mod the pipe and get an SCT with a tune to shut off the EGR operation.
It's well worth your time.
