1st, don't trust the stock boost gauge. 2nd, for about $5 you can build an adjustable wastegate rod. Intsructions are here: http://gnttype.org/techarea/images/Adj_wastegate.JPG

Be Careful!!!
Make sure you are accurately measuring boost, then slowly walk it up in 1 or 2 PSI increments. If it's pure stock on 93 octane then 15-18 PSI may be all you can safely get by with.
That extra air is going to need extra fuel, sometimes the stock fuel pump isn't up to the task. Be careful.
Detonation is the demon.

Well, once you have a boost guage, you're going to need a boost controller that works with the stock wastegate actuator arm to increase the boost(if you want to be able to go back to stock). I have one left for sale right now if you're interested at this link: http://www.turbobuick.com/forums/showthread.php?t=182302
You many need to increase your fuel pressure, or purchase a chip as well to make sure you don't lean out too much and detonate. As they said, stock boost is 14psi, but the stock turbo is fine to ~21psi, then it starts blowing hot air, and is no longer worth increasing.
Hope this helps you.
