Congrats on your new ride. Pictures are mandatory, so post 'em up or else people will start giving you a hard time. Sounds like a possible boost leak which could be any number of things. Intercooler o-rings are one of the more common problem areas. The wastegate could be the culprit as well, though I would think a leaky valve is more likely than a tired spring.

Do a search on "boost leak" and you get lots of hits. Stock gauge accuracy is debatable. Most folks recommend putting in a mechanical gauge and trusting it rather than the stocker. I've found that my factory gauge is reasonably accurate at telling me what max boost is, but is very different from the mechanical gauge as far as how and when the boost builds. I believe that is also a function of where the pressure is measured (stock = before throttle plate / mech = after throttle plate).
