The EGR is actually a good thing. It helps emmisons at part throttle and keeps combustion temps down as well as fuel mileage up. It shuts off at WOT so there is not really a need to get rid of it. You need to program it out if the chip or you will throw a code.

I got rid of mine with a billet aluminum block off plate from custom billet works. I'm not a huge fan of carbon build up on the inside of my intake and ports. Also removed a lot of crap from under the hood. I say remove it, but you must also delete it from the chip or it could cause detonation problems. Also, if you have a good flowing exhaust, the lack of backpressure can cause problems with the egr valve which I didn't like either.

It can cause it to not open or close right. That can be fixed with a negative pressure EGR valve found on some older trucks. It is very rare though. I never had problems and neith did my buddy. That doesn't mean it can't happen though.
