Today, started having some problems with the car. It's not highly modified. Basically uppipe, exhaust, BOV and turbo boost. My problem is this. The turbo seems to vacuming all the time, except on acceleration where the turbo hits it's 15psi. But the boost gauge reads vaccum all the time. Even when I am stopped at a light, it reads that way until I take off. and when I do drive, the BOV seems to be venting gas way more than it use to, if i slightly decrease throttle, well i hear it. Was wondering if anybody could shed some light on what the problem could be.

All help will be appreciated

do you mean it's boosting when you're accelerating, but when you let off...you get vaccuum? if so...that's normal.

 

I knoe it's suppose to vaccuum, but not when you are stopped. It's vaccuuming when I'm at a red light, at something like -20psi. and as I said, it seems to release air from the BOV way more. Could I have a leak somewhere? Also, acceleration is very bumpy in between 3k and 4k RPM

 

at idle, i'm pulling around -17

 

Found the problem. Had a very dirty air filter, made the car feel very different. The rest, well that was all paranoia. When things feel wrong, you tend to notice things you didn't think were there before.

Thanks for the feedback

 

I used to worry about this all the time too when i first got my car. I saw it was constantly under vaccuum untill I was accelerating and thouht something was wrong. It's really nothing to worry about. As long as your not accelerating the car will remain in vaccuum.
