The OP tried it and he creeps to 20# from 15#. So, if he adds another 4-5 PSI of preload on top of the 15#, I think that he should peak at 19-20# on the wastegate and creep to 24-25#, which is his target boost level anyway. If however it were to hold at 19-20# and not creep, then he could just add the 5 PSI with the MBC.
EDIT: One thing at a time. First we'll try to solve the extreme taper swing down to 15 PSI. If it still looks to creep, that would be another, separate issue.

EDIT: The IX turbos are notorious for tapering and the colder weather will tend to cause the turbo to creep.

well with the controller turned all the way down it hits 15 then creeps to 20
