I have compressor surge and I think its because of my BOV (tail Q) not opening after letting off the throttle. Also my car dies if I let off the gas I have to keep pressing gas to keep it running. Are these problems related and can I clean the BOV? The vacuum line from the BOV runs to the TB and seems to be holding up
 
3 ya, those are metered air leaks. Google "boost leak test" and do one. Those need to be capped, and you may have more. At the very least hook the bov up to one of those that has vacuum and use a piece of hose to route one nipple into the other. That will effectively cap the two and make your bov work properly. You'll know ot has vacuum on the port when you cap it off with your finger, or you can use a boost/vac gauge and hook it up to the port and take a rwading. Any port with manifold vacuum is OK for the BOV.

If you like loud BOV sounds you're going to like when that thing goes off properly. I love mine!

Thanks, Im currently tackling a no-start issue with the cas or cps being the suspect, couldn't that explain my stalling issue? But I have capped those 2 nipples and as soon as I my car running ill post what happens..

And the loud BOV sound is what I am aiming for. I want people in their homes looking out the window like, wtf was that :idontknow:? but can't I get in legal trouble for audible BOVs?
