I wanna buy the HKS SSQV3 BOV hardpipe kit from Z1 motorsports: ([ http://www.z1motorsports.com/product_info.php?products_id=2525 ]{1}317{6}328{19}818&osCsid=731e8a32baa6cc7c00504a94bb6c89c5). But I don't know how good they will perform. I'm seeing in other forums that BOVs can actually hurt performance because they release air that the engine could have used, which tricks the MAF sensor into thinking that there is more air in the engine than there actually is. And my question is if this does actually hurt performance is there a way to make these HKS SSQV3's into RECIRCULATION VALVES so that the air is not lost? If so, how and is there a tutorial page somewhere? Thanks in advance...
