As for BOV...my stock BPV was running fine and I was boosting upwards of 23-24psi in the cold weather during WOT pulls. I was tuned to 21psi and it held out fine. If you are planning on upping the boost any further than you have, looking for a better recirc BOV would probably be a benefit for you. Most people will say that the stocker is good til about 20psi.
btw...LOL at Justin...damn good observations.
