I have been driving with a bit of solenoid buzzing/farting for over a year now
No boost issues, but I am thinking of replacing them as preventive maintenance as my warranty expired recently.
IF you are not having any boost issues, then just leave them at 90% and live with a bit of wastegate rattle for now.
After all, you only hear the noise when you have the hood open so who cares?
