8.7 WG spring and all a sudden no boost past 4psi?!?!

What is going on? I've been driving perfectly fine at

8.7 psi for awhile now. all a sudden tonight i turned

my car on to leave and i couldn;t boost past 4psi... all

the gears i checked, no boost past 4. I checked all

the vacuum lines and the couplers i can see, and

they LOOKED fine. My BOV doesnt make sound at

4psi anymore like it use to.


What should i check, or check again?

Is this something i shouldnt be too worried about?

PLEASE HELP

maybo it's your bov...
got a bit stuck open maybe ???

bov or piping somewhere... check ALL couplers... not just the ones u can SEE... check the coupler coming off the turbo... those seem to rip often. any holes in ur ic piping can create this... even if u tried to turn up the boost it wont boost ---- and u'll prolly blow the turbo cuz its actually flowing a grip of air but its jus not making it to ur intake manifold because of the hole somewhere... keep looking buddy

I need more help, i dont know wat going on!

performance shop dont know they said maybe be

fuel problem, just a guess, and josh said its possibly a

boost leak somewhere.

Should i check/ open the WG change the spring or

re-adjust it.

remember it doesn;t go pass 4 psi. its even slower

than the motor stock. Once it hit 4psi, it stays at the

powerlevel, doesnt pull any more. Takes forever to

hit higher RPMS.


ANY SUGGESTIONS?

so did u check all the vacuum hoses and couplers CAREFULLY???
if it is only a hairline crack, it might be able to hold boost until certain level before it goes.
