Well i just got done putting together my car..

[GettinPaper]

And it run's great and everything but it seems to not hold boost?
I think i might of messed up with the vacuum lines?
I just removed all of the ones that are uses on the gold bracket underneath the
intake manifold, and i have a mbc hooked up with it backed all the way out.
and it's tapped into my j pipe also.
so i don't know what would cause me to not
hold stock boost??
I need help please.

Check your mbc vacuum lines and make sure they are routed correctly.

Well the bottom vacuum line of the MBC is going to the waste gate actuator, and the top vacuum line is going to the tap in my j pipe..
But i will over look them and see if there tight.

This is the proper routing. Try screwing mbc in...Seems like your vacuum lines are reversed....
