ROFL..... you really should stop asking for advice if you're just going to ignore it.
You have a couple options: Ditch the BOV for a BPV. Connect a BOV AND a BPV OR find a dual outlet BPV which will recirc one of the two ports and blow off the other at the same time.... they *help* for half the build and for the other half they don't make a difference... they're pretty hard to find and I think they're pretty expensive. The only other option is to buy a fuel controller with throttle tip-in and tip-out tuning and get the system tuned for it.
Timing isn't going to do shit but cost you more power and has absolutely NOTHING to do with how much fuel the ECU thinks the engine needs. No, newer BOVs do not let out any less or more air than older ones... it depends entirely on how the BOV is tuned (if it's adjustable; a feature even many old ones had). There isn't a design out there that I know of that is so vastly different that I'd believe that line of crap.
