still don't understand bov
Maybe I'm thinking to hard on this or something. I've read through all the bov threads, the faq, and searched. But I don't understand how a BOV will cause your car to run rich. Whats the theory behind it? I need to pro-tune on my car, and about to get it done. But what I don't get is how the BOV cause's your car to run rich? I understand that it's design is to release pressure after a set point, and make a cool sound. Please explain this theory or direct me to where I can read up on it.
