Exactly.
This is SR20 101 - not some miraculous discovery.
All of you should be good little turbo car owners and should still have your crank cases hooked up to vacuum already...
I don't know why anyone would have ever removed the stock setup- Nissan did that, if not anything else on the (T) series motors for a reason.
At higher boost and HP threshold/levels you can see gains of 25-70 whp...cough
