RE: AFM's and MAP
These are the two ways in which your car works out how much air your motor is getting to find out how much fuel it needs to give to achive the correct air/fuel mixture!
An AFM is an "Air Flow Meter", it uses a flap to work out the volume of air the motor is reciving (They look like a black/silver box with a filter on one side and the other connected to the inlet manifold).
(venting air through a BOV may effect the AFM readings and this could confuse the computer).
MAP senses the "Manifold Absolute Pressure" to work out how much air the motor is getting, the higher the negitive pressure the more air the engine is getting (sucking in), hence the more fuel it should be given to achive the correct mixture.
I pretty sure you have a MAP engine so you don't really need to worry about the venting BOV thing....I think? (not the real turbo guru!)
