Unless you're putting down serious numbers, a BOV is unnecessary, and more than likely, more harm than good.
A 100% VTA will be worse than the hybrid (50/50). All-in-all, it's your car, and your call. There are countless threads about BOVs on here, so do some research and make your decision.
Our cars were designed to work with recirculating BPVs. If you want the "PSH!" sound, get a K&N Typhoon SRI or do the silencer delete. Alternatively, go StageII.
