You will not gain any HP from a BOV. If you know what a BOV does, then you should already know this but a BOV releases air trapped in the intercooler piping when the throttle body is closed. Without a BOV, the trapped air would come back through your turbo, otherwise known as compressor surge, and that's not a good thing.
