low boost problem...help

[soobturbo]

i installed a turbo xs boost controller for about a week
i then decided to remove it because i just ordered a cobb access
the problem now is im only running about a
half of a bar of boost(7lbs+/-)
the vacuum lines were reinstalled correctly, they have been checked by three different people now.

any ideas??
any and all help would be great

thanks
