boosting low

okay, since i was having major problems with it, i took off my mbc completely. im not sure i did it correctly though, as i wasnt the one to put it in. does anyone have a closeup picture or diagram of the actuator and surrounding hoses? i want to make sure i didnt foul anything up.
i went for a test drive just now... and im boosting only 8psi in all gears. i tied down all hoses... maybe not tight enough? maybe let the ecu adjust?

help!!!

Check this install of an MBC on ScoobyMods.com. By reversing the order of installation, you might be able to figure out how to put everything back. Also, one of your factory boost control lines contains a small restrictor bleed fitting, usually made out of brass with a tiny hole drilled through the center. This restrictor bleed is inserted inside one of the factory vacuum lines and is easily overlooked. If the line with the restrictor bleed is not used, or if the line is replaced in the wrong position, boost will not exceed what you are presently seeing.

EDIT: amended 'bleed' fitting to restrictor bleed'.
