I have brand new stock replacement turbos with the upgraded wastegate components and the car was rattling like crazy. I went into the JB4 FUD options (click on the "bits" tab under user adjustments) and there was an option for "alternative wastegate position" which set the FUD to 128. I went to setting 10 on the speedo and set the RPM setting to 5 and the rattle is gone. Boost response is great too.

I think the jb4 settings just needed to be tweaked.
