well a few things are going on after I drove the car down the block. Vac is reading 18. Is that normal(in fla). My bov seems so wine a bit after I get off the gas. does that mean i need to tighten it?(greddy type S, vac line in the top port) and i've gone up to 5k rpms and still the gauge won;t reach boost but I feel the car pulling. I have a Turbo XS duel stage BC and the ***** on both are completely closed. if I had the vac imput and output lines backwards, would this cause the problem? thanks for you quick responses in advance

 

The bov probably just needs adjustments. Check your vac lines on the MBC to make sure they are correct, either that or your boost gauge is broken.

 

check the lines for the boost gauge, make sure they aren't pinched.

 

im gonna try that now thanks for the quick responses. keep em coming.

 

bump for some help
