What are the pros and cons of doing the EGR block off modification?

i really dont think it does that much.... at certain times (not all the time) the engine puts some exhaust into the intake to balance the gases, its just a small amount so i dont think it'd make a big difference...

I know that is really hard to understand, I cant really explain but i tried.

This is a short article about the EGR that defines it. http://autorepair.about.com/od/gener...l/bldef165.htm
I just had a problem code P1406 which happens to be the EGR or circuitry for the EGR. I'm guessing somethings broken and the EGR doesn't work. I have had NO problems. It actually seems to run better.

not sure about this but if you put a block off plate on the egr won't it set off a check engine light? My theory behind that is that the computer will detect a lack of flow through the egr and set the egr low flow code. Not sure if it will actually do that just a theory.

i dont think it would be that big of a gain at all...

theres really no pros or cons to blcoking off teh egr

theres really no gain its used for emissions purposes only

some say that teh engine temp may be slightly higher when removing it , but im not sure
