Correct, removing the EGR will do what you stated Manybrews.
What does happen when you remove it is, you remove any chance of vacuum leaks, you stop recirculating carbon, and that's one less thing to fail in a DSM.
I agree that it doesn't add HP, I never believed that either. What does that do for HP? You don't add HP, you only regain what was already there when you remove the EGR and Seafoam your motor. Raising engine temps, sure, but there are other things that will help lower it if you're really that concerned with it, but your engine temps don't go up enough to worry about melting things or knocking. Ping, is something you say about N/A cars, knock is what you mean I believe, Manybrews. That can be countered also, I've got alky injection on the boards as my next mod. That will help lower knock and raise my octane (that in turn will lower knock even more, which I don't have anyway). Gas milage? If I was that worried about it, I'd have a Toyota hybrid and not a 50-75lbs heavier than a GSX Avenger with GSX parts. Most DSM owners feel the same way, if they didn't, they would be buying bigger injectors and turbos, IMO.
If any of you get a chance, take the EGR valve off and scrape it with a piece of wood, a stick. Measure how many MM of carbon you just scraped off, now imagine that throughout the EGR's route. How much does a new EGR system cost? What does that do for HP? You don't add HP, you only regain what was already there when you remove the EGR and Seafoam your motor.

This thing gets really clogged up, it's about $88.
..but anyway, there's counters to both sides.
Here's some good reading about the EGR system and where the myths were first told.
