my talon didn't really have _problems_ back when i tried venting mine, but the car did run rich according to the logger. the fuel trims jumped all over the place with it vented, it was a nightmare to keep up with it on the S-AFC...
no matter which BOV you use, you can't get around the fact that'll it'll run rich after it blows off. you're releasing metered air out of the system, the ECU expects it to be there because the MAF has counted it already...
my CBV is plumbed back into the intake, the sound isn't worth it to me.
