Is it true that circumventing the EGR system will lend more power? I have to fix part of it anyways for emissions but in the course of my research I found out a lot more about it, and I'm thinking of circumventing it after my inspection.

Since what it does is recirculate a small portion of exaust gas back into the intake system, it should lessen the power output of the enigne a little, right? I was thinking of just plugging the vacum setup that operates the system after my inspection, to get a little more power out of the car, and it because it really serves no purpose (it reduces NOx but at the same time increases carbon emissions).

I was wondering mostly if anyone else has bothered with this and what the results were.

The EGR only works at part throttle. At full throttle, it is closed and doesn't affect power.
