Blow-Off Valves

AWD, you don't care that it'll make your car run worse unless its a dual vent?

ok well since i know nothing about BOV'S i had no clue u could lose horse power so lets not all get our panties in a bunch here. I was just trying to do some research to find out so i'm glad u guys could help me out. How much of a power decrease is it? Is it noticable?
thanks again!

if you get one that vents to the atmosphere, then your car will pig rich when you shift because the mass air sensor is seeing air go past it, but it's getting released from the intake tract into the atmosphere. the computer sees all that air and puts in the according amount of fuel and when you've got lots of fuel and not very much air, well, i think you can figure out the rest. basically your car will stumble when you shift and not run well when you let off the throttle abruptly (ie whenever that BOV cracks open hard.). so unless you HAVE to have that sound, and especially if you want a performance mod, skip the BOV. and TFATF for that matter.
