BOV setup

Got my brand new shiney(well matt black) GFB blow off valve in the post today . this one has 3 different set ups on it.

1. Full re-circ: same has factory one, very quiet
2. Hybrid: 50vent 50 recirc, noticeably louder
3. Atmosphere: 100% vented, loudest option.

Can anyone explain the driveabity issues between the different setups? 50/50 seems to be the common choice

Shouldnt be any noticeable difference in the driveability of the car with either choice. With the 50/50 and full vent to atmosphere, the engine will run rich when you let off, or change gear and you can get some pops and bangs caused by that
