You need some Engine Management. Get a Cobb AP or a decent protune.

...emphasis on the .3

Anything higher than that and your car may turn into the out of control commuter bus in the movie Speed when it hit 50 mph or the time machine DeLorean in the Back to the Future movies when it hit 85 mph.

In all seriousness though, engine management is a good idea to keep your boost in check.

My 09 hits around 14 at peak boost... Should be pretty accurate as I read 22 in/mg at idle and right around proper boost stock.
