I posted this question in another thread. Rather than start a new thread, I thought I might also post it here.

How active should the BOV be? Lately I hear my BOV a lot. Like every couple minutes while driving on the expressway.
The BOV should only activate when you lift off the throttle and create vacuum in the intake manifold. Although at cruising speeds you don't really produce much boost so the BOV can float if you are on and off the throttle a little bit.
