Please help. Turbo acting strange

[civileclipse]

Okay.. I usually run my 16G turbo at about 13-14 PSI, but I recently turned it down to about 10 PSI to take it easy on the turbo until I really needed it.. Anyways.. Today I was boosting, nothing major then all the sudden the PSI just dropped to nothing, it was like i let off the gas, but I was still pushing it. So I let off the throttle and tried again, and it hesitantly spooled to about 6-7 PSI, then dropped off once again. I didnt see any smoke, smell anything out of the ordinary.. I checked the hoses to my Joe P MBC and everything seemed fine.. Please help.

Most likely a boost or exhaust leak.

But why would it happen all of the sudden? I have had no problems until the last time I drove it.. and out of no where it does that. Also, is it okay if I drive it as long as I dont get into the boost range?
