You will never get your 02s to "settle". They're meant to oscillate. Actually, the fuel trims are meant to oscillate, and the 02s reflect that.
Catalytic converters need alternating rich lean rich lean to supply the catalyst bed with alternating (high, low) levels of oxygen as well as hydrocarbons.
You're long terms are very negative.
I haven't looked at the tune yet.

Ok I was just watching a friends stcok truck and the o2s where pretty smooth at idle. I have tried to to the VE table tuning but the car will surge really bad is that normal?
Your fuel trims are way off. I didn't look at the tune yet, but it looks as if the injector flow rate is off.
