EGR removal
now before anybody says search i did search through 12 pages of criteria and found tons of opinions and what to do when you removed it but not an actual thread that says how to remove it and what to block off if you leave the assembly on does anyone know of a thread that goes into detail or has a picture of what to block off thanks..

or, pull the vacuum line into the egr and plug it.

You may have seen my suggestion of using a rubber stopper, cork, etc. to plug the pipe. I realise this isn't the best option, it will deteriorate in that environment. Mine was a spur-of-the-moment decision, requiring minimal effort. I was thinking good vac seal, which is critical, so I wanted to re-use the gasket. I have the metal plate method on my list of near future to-do's. Some high-temp oxy sensor safe RTV, oughta seal it up nice, or maybe some bulk gasket mat.

It all depends on how that pipe is routed into the plenum(intake). Can the pipe be removed? How? If it can't be, you should still be able to get some effect from disconnecting the EGR by pulling the vac hose at the top of the unit, and in this case I would recommend a stopper to plug the hose end. It is better to get that pipe outta there too, if possible.

Yeah, Imma pull that hose and test it. Bout to drive over to the girlfriend's house and its a ~50mile round trip, so I'll let you know what happens just by removing the hose!

It could mean that your EGR isn't working, kinda like turnin' a light off, that's already off. See what I'm sayin'. You should also plug the hose, so it doesn't suck in debris, it's a VACUUM hose. The effects could be less dramatic with varying engines, good thinkin'. Oh, and if it isn't functioning(EGR) your work on that project is done. Because it could only fail in such a way that would do what we're dicussin' for ya. If it was the other kinda broke you'd know. Failure is either a stuck open/closed deal, functionaly.

The EGRs purpose is to reduce combustion temperatures and thus limit the formation of different Oxides of Nitrogen (NOx) which are very toxic gasses.
If you want to increase performance, why don't you look at increasing the pumping efficiency of your engine?

Not only will you likely not gain any performance by disabling your EGR but it will not increase the output of greenhouse gases.

Higher combustion temperatures = detonation/ retarded timing= less horsepower.
I think you need some new study material
Unless you are looking to do extensive powertrain management alterations you will not benefit from EGR removal.
Good luck

O.K. , I'm back and look what with. Pay due attention to the part that explains, how GM decided to sacrifice power and fuel economy, in order to fight smog(oxides of nitrogen are also considered GREENHOUSE GASSES).And the part after, using the analogy of a "fire-extinguisher" in the description of a device to perform the funtion of the yet undeveloped EGR valve. Brilliant! Just what I wan't flowing into my combustion chamber!FIRE CHAMBER! I think that's whats missing here.misterfixit.com/egrvalve.htm Should add too, I've never heard of anybody getting "pinging" from the by-pass of the EGR. :complain:

questions for the Mud Hippy...
Eliminating the EGR helps MPG? or hurts it? Better MPG is good against global warming too, last time i checked...
will disconecting the vacuum tube on the EGR valve shut it and thus prevent it from being used thus make removing it unnessesary?

Helps.That there be the TRUE issue, or was at the time of emmissions control regulations beginnings. There is a sound arguement in favor of the view, that states more MPG=Less Emmissions. I don't see how that could be wrong, do you? I just happen to have been born too late to chime in on the decision making process. Lucky them, because this Hippy nah so dippy. And , yes that way will work to get the by-pass accomplished.
