BOOST GUAGE!

Hi all,
My 93 SSEi does not get full boost. The guage will only go 3/4 of the way. Reaching 70 is never achieved. What can be the problem here, and how can i fix it?
Thanks

Well, look at that pic!! I'd start there...

Sounds like it may be a wastegate issue... check vacuum lines, and such, thnen move to possible coupler or bearings, or simply belt slippage.

Could be just getting tired....

Coupler won't cause this, but belt slip, air filter, gummy bypass actuator, dirty TB, bad BCS are all possibilities, along with the vacuum leak.
