i had a hks bov with the intercooler pipping i tossed that and put the stock one back on and put a aps bov. for a few weeks the stock pipping kept popping off the mani every time i boosted. i somehow fixed that problem but now when i boost i hear like air is coming out of somewhere but the reading on the boost gauge says im at 17psi, which is ok since im pretty much stock and its very hot where i live. i was thinking maybe i have to adjust the bov what do you guys think?

 

You may have a leak in one of your turbo hoses. Also check to make sure that all the clamps and hoses are secure. You may also want to upgrade to some t-bolt clamps.
