ok so I'm on my second BOV now and niether one of them have worked...my first one was a knock off greddy and was brand new...now I have a DSM one on there now that was being used two days ago and worked fine but now its not working on my car...I have the vaccuum ran to the top of the throttle body with my boost gauge tee'd into it and my boost gauge works fine...could it not be getting enought vaccuum or what...?

 

if you've done what i think you did, that port on the throttle body does not have vacuum. Vacuum comes from anything after the throttle plate. Does your boost gauge read vacuum as well? Or does it work only when your boosting? Try moving the vacuum source to a port on the intake manifold it self.

 

u know come to think of it I think it reads very little vaccuum and I took that vac hose off while the car was running and it didn't change anything....I'm gonna try that tomorrow and see if it works... Thanks

 

ive learned little **** like that the hard way lol.

 

LOL yea I didn't think that was pulling much vac...
