Its normal when stock because they dont vent it to the atmosphere they recirculate it.

I would imagine there is way to make it vent without buying a new one but I havent looked into it yet.

^^^ this is correct. Most of the aftermarket blow off valves are aluminum and have the option to vent to atmosphere. The problem with the stock BOV is that it’s plastic and can warp when exposed to high heat causing it to get stuck open/closed.

the boost psi can be adjusted by loosening the wastegate. If you go on Aftermarket Assassins website and poke around in their “tech blog” you can find how to do that. You would need a tune adjust it otherwise your machine would likely throw an “over boost” code from what I was told.

 

I know its an old post but I wanted to correct you regarding wastegate adjustments. You're not actually loosening the wastegate. That would decrease/make it easier to open. Adding pre-load (tightening it) to the wastegate spring effectively making it require more pressure to open. You're basically changing the cracking pressure from 4.5-5psi (stock) to 6-7psi. Just hope it give you a better understanding on how it work

 

Your boost controller manages boost pressure with the ECU. What is on the AA site is to adjust the wastegate crack pressure to work with their tune where they have modified the boost pressure the ECU is calling for among lots of other things. I would not recommend adjusting your waste gate unless you have the necessary AA stage 3 or higher tune and other hard parts.

 

Thanks for all the info.
