did you do the install yourself? First off I stronlgy recommend getting an intercooler. You don't need to get an hks or greddy, a blitz isn't too expensive, or you can get even smaller and get a spearco. I would need to see the setup to know why your boost is rising, have it looked at, with no intercooler and the possibility of a boost spike your motor will be toast. As for the lower vacuum connection I am not entirely familiar with it, I personally don't use bov all the time since they are really a audible mod, no use for low boost low hp applications. Maybe that is your problem?
