Idle fuel mixture, Lambda and boost enrichment are all independant functions.
If you are rich on boost there can only be a handful of causes:
- blown O-rings intercooler/throttle body (vac leak)
- fowled spark plugs or weak ignition
- worn out WUR (which you have tested)
- using a modifed fuel head when you don't need one
