your wastegate is just what it's name says, it takes the extra exhaust that is not needed to maintain your level of boost and dumps it to the atmosphere or to your exhaust pipe, depending on you you have that exit routed.......the wastegate is mounted inline of your turbo's on the exhaust piping.......the bov is lined up on your air inlet to the engine, this helps ensure that your turbo's don't stall or spin backwards when you let off of the throttle........so your wastegates are releasing exhaust and your bov is releasing air.........if your bov is connected right, it will get it's signal from the intake manifold and the wastegate will get it's signal from the turbo...........that is how i set mine up and it seems to work very well..........without actually seeing your set up, it is kind of hard to help to solve your idle issue........anyways, i hope that helps in the understanding of a bov verses a wastegate..........if i can help with anything, feel free to ask, later, hotwheels of turborides
