Subject: Re: 9000 CS low turbo boost

Does it have TCS? If not, it may be a dead BPC valve. Just did this on my dad's '94 Aero. We verified it by swapping a known good one from my car. A new valve is spendy, a used less so, but it is unknown. See if you can find a kind soul to loan you his known good to check it out.
