It definitely allows the turbos to spool quicker too. It's a cheap win/win mod.

I never had what you described, drone moving up in the rev range impression. Of course, it may be so because I had N55 mids installed at the same time with Evolve rear. In the begining there was less drone with new set up and after a few thousand kms. I have none now. Every car can be a bit different too.
