He has a pocketlogger. I say, tune from the readings of knock from the pocketlogger, not the factory boost gauge thing. Forget about the o2 readings, at least until you can get an new one, but even then you should be tuning from your pocketlogger knock readings. What do they say anyway?

Well then why is he screwing around with the o2's?


Use knock man. Tune till you have no knock. It's not hard. Your o2's could be .000001 repeating, but as long as you have no knock and good timing you are all set.
