I was gonna plug the hole in the exhaust and i have a 1/4" aluminum plate all cut out ready to cover it. I've read the egr debate. I dont quite understand whats good about it? Except for the enviroment. As far as it burning more oxygen and making bigger explosions thus higher engine temps raising possible detonation, isn't that the same as boosting the air density? Since it only works when your cruising, wouldn't WOT immediately cause detonation? I mean the explosion in the chamber is gonna be higher at 12 lbs of boost than with the egr at N/A? I am not bein smart. Thats just my understanding. I am open to opions
