From a performance stant point haveing the egr on or off make any diff in power or driving, Just trying to under stand why so many people tune it off.

 

There aint no performance gains man. Most guys remove it while they are there like me. Its just something less to worry about.

 

EGR is one of those parts that people complain about all the time and can even cause the dreaded low rpm stumble so i just got rid of mine along with the air pump. i just figured it would make my life easier when it comes down to diagnosing problems.
