2g->1g BOV: adds 4 psi?

[Semprini]

Does the 2g bov leak that bad? The only boost mod I have is the BCS freebie. Even with the stock bov it would boost and hold between 14 psi, which sounds about normal. I just installed the 1g bov I bought from a member and itll boost up to 18.. Im confused.

ps I searched and didnt find much on this hence the post

thanks

Ok I finally got the hallman on and it solved most of the problem. It doesnt spike nearly as much. In 3rd and up itll jump to 17-18 then settle back to 16 where it is set. I know I also have a boost leak, the adapter I bought for the 1g bov is crap and does not fit tight in the stock upic. I used the stock vac lines and the stock locations.

It is probably better to spend a few extra dollars and replace the stock UICP than to spend money on a BOV adapter. I am using a Dave Brode UICP and I am quite happy with it. I spent some time to sand it, prime it, paint it, paint it again, then clear coat it twice, with 1000 grit sanding inbetween. Game out really shiney. And it was fairly cheap ~$60 if memory serves me.
