In response to kellygnsd, I don't have trouble keeping my boost down anymore. My issue now is inconsistent boost. I set my manual boost controller at 19psi, than the next day it will be 1-2 psi higher or lower.

Do you have access to a 3 port bcs you can swap out and try? Its almost sounding like the spring in ur MBC is not holding properly. I had a buddy with a boosted civic that had a problem of the vibrations in the enigine would rattle the MBC alittle. did u get it used? almost makes me want to go out and un hook my 3 port and see if I go over 11.60 because i have the same sping in.
