IMO your build would benefit from a vacuum pump more than most other motor mods you could do at this point. It's usually good for ~5% power gain.
All I know and care about it that it works for the exact reason I bought it which is to catch oil and water so it does not recirculate back into the intake system or back into the pan like the grimmspeed aos does that I was previously using...

I followed phil @ element instructions to eliminate the pcv all together to help evacuate crankcase pressure as quickly as possible and it works!
