Did anyone ever find out for sure if our stock BOV is leaking boost? I did a search but couldn't find out for sure..I know some people were going to put an aftermarket bov on and see if it made a difference...just wanted to know if the stock one is really leaking or if it is just inaccuracies in the boost gauges..

thanks
 
Yeah, I think they do..but I've just read that people think its leaking somewhere, not sure exactly where though..
 
what boost are you at with your gauge. where is the reference for the boost gauge coming from? and does your car have a problem running?
 
My boost gauge reads in hkpa and it usually hits around .45-46 when I'm fully accelerating..so I think you multiply that by 14.5 or something to get psi. I'm not sure where the Blitz gets its boost reading from, I'd have to go check that out since I didn't install it...And my car is running fine except for the hesitation/stumbling in 2nd and 3rd around 4-5k rpms.
 
i dont! DO I HAVE TO MAKE A VID! I hit about .70-.71 bar and by about 5500 rpms it will go down about .55-.52 bar. right before redline it sometimes goes to .48 bar.
