can i remove the egr valve?
What would happen if i removed the egr valve. This motor is going to be used for "weekend racing only" it will not be daily driven, and is going to have a chip custom burned for it.

I removed my EGR when I had the plenum off. I put a plate over the hole in the manifold and sealed it well. I had to get shorter bolts as my plate wasn't as thick as the base of the EGR. That and plug the vacuum line is all there is to it. Motor still runs cool. No codes either.

Re: can i remove the egr valve? (sdixon)
I junked the EGR on my L98, and have had no problems until last week. I was driving home across Spain and it was HOT outside. The "ext temp" showed well into the 90's, and I was pushing on at about 85 - 100 mph for most of the day (10-15 min stop every 90 mins or so) Sometime after midday I got the dreaded "service engine soon", so I pulled the code - 32. This told me the computer had detected a fault in the EGR system (which I thought was pretty impressive since the EGR system was in a cardboard box at the back of my garage a thousand miles away!).
I cleared the stored codes, set off again and ten minutes later it was back. Let the engine cool for 20 mins, all OK, 10 mins fast running - code back again. I decided to ignore it, and the next day, when it was cooler, never got a problem.
This is the only time I have had anything like a problem, and the car ran + felt fine - I think you can safely junk it.

I removed my EGR system and haven't had any problems. I understand you CAN get an error code under some conditions. J. Kovitch has some good info at http://www.geocities.com/jgkov/index.html. One article is how to fake out the ECM and make it think there's a functional EGR out there under the hood. He has other good info, too.
