atmospeheric BoV's can screw with your MAF and ECU by letting out to much air and make your car run lean, so try and stay away from them unless you have a setup running 20+ PSi.

How does a blow off valve let off too much air? It's meant to release all of the excess pressure from the turbo before the intake manifold right?
How does letting out too much air make a car run lean? Less air, but same amount of fuel would make a rich mixture. This can lead to excess carbon build up in the cylinders, faster deterioration of cats, and back fires, but not running lean.
And whomever says that this kills gas mileage is wrong. You're putting the same amount of fuel in, but less air causing it to be rich. So, whether you run a recirc or an atmospheric, you're using the same amount of fuel in the mixture. People drive differently so they can hear the bov more which causes worse gas mileage.

Yea,...every time a jack off in a Neon revs next to me to show off his BOV I want to send an RPG up his ***...
I F'ing HATE BOV's.

It lets out air that has already been metered by the MAF thus creating a rich condition. Thats why you shoot fireballs. As far as letting air out before the intake manifold... huh? Well yes, but its more like throttle body. The bov allows pressurized air to escape before hitting the throttle plate and bouncing back to the turbo causing damage. Also known as compressor surge. See the throttle plate closes before the turbo stops producing pressure.
You guys need an edubacation in turbo systems.
