Here's a quick MS Paint drawing of the underhood vacuum chart. The two lines in green are the two that I retained. In addition, I have one line from the intake manifold over to the heater valve by the charcoal canister, and one line from the throttle body down to my wastegate. I have another one ran to the blow-off valve which isn't shown on this chart.
All of the metal hardlines are gone, and the few things left over (the two on the throttle body that aren't being used) are capped off.

I pulled out the whole EGR for a few reasons, in this order:
1) Just one less thing to screw with when changing plugs or cams
2) Weight savings
3) Performance? People mentioned better throttle response...I didn't really notice anything, but I probably don't drive the car often enough to notice small minute changes.
I kept it all in case i need it for emissions, but it seems that the general consensus is that you should be fine as long as you get the cat hot-enough prior to getting sniffed.

To answer the question about the VSV - Ieft it in place plugged in, but it's not hooked up to anything.

I had o2 sensor and egr codes, and after I replaced the bad o2 sensor and instaling egr blockoff plates from mvp motorsports. My engine keeps on doing this (rrrrrrrrrriiiiiii) sound when I step on the gas pedal.all of this happen when the engine warm up not when is cold and is waiting fuel like crazy
