King, everytime your post are so summarized, why don't you elaborate more with some logical explanations ??
fair enough....but this one should be more common sense than anything, no? hot air into the intake = less power. Then, take into account the fact that the rotors in the superchargers create a lot of heat when pushing the air through, and the efficiency of the supercharger is then even worse than it already is.
from the wiki post that you made in the past, all the theories make sense, but they don't go hand in hand with anybody who is trying to make power from their car. YES, having a good egr can allow better mileage by lowering combustion temps since there is less oxygen (and timing is advanced), but that also results in less power (for more power, adding enough fuel will allow timing advancement). Perfectly fine for a stock car, but for people who are slapping on FI and looking for power....that's for that person to judge for themselves.

1. Yes, the egr definitely robs power. Unfortunately, your assumption is wrong. There are two ports at the TB for the egr- port E and port R. At low throttle, only Port E gets vacuum, and the EGR valve is closed. But once throttle is increased and the butterfly is either between the E and R, or both is open, then, the EGR is then open and circulating the exhaust gases into your intake. When both port E and R are open, there is even more exhaust gases entering your intake than at less throttle and the butterfly is between the two ports.
2. Nobody is exempt from emissions. Some people just find ways to deal with it one way or another. Also, it's not guaranteed that one would fail emissions without an egr. Just, chances are a lot higher.
3. This is the one statement that I agree with here. But then again, I've bitched at Adam before about not covering it up with electrical tape, though it technically makes no difference and unless it hits a live wire with decent voltage, it won't short out. Even water makes no difference.
I hope that clears up some things about not running an egr
