I've got a monk attuned to the Dragonhide belt+1 but it does not affect the save DC or any of the other saves on ki abilities. I've unequipped, unattuned, etc but having it on or off does not affect the DC which is referenced by the other ki abilities on the sheet.

This is a known issue, magic items can't affect (sub)class feature save DCs. The system overhaul in progress will help make it possible.
