Default Problems passing Emissions tests

Hi;

Recently, my Z51 LS2 C6 failed emission testing because to many of the IM tests weren't "ready". I have three tests showing not ready EVAP, Catalyst and O2heater. The car also has pending/immature P0141 and P0161 codes (rear O2 sensor heater circuits) showing, but no MIL or SES lamps illuminated. No other codes showing. I'm thinking my rear O2s are shot ... and because of that, the IM tests wont complete.

The car has an A&A supercharger setup and stage two cam ..... which I've had through emissions testing successfully in the past....when they used the sniffer setup. now they've switched to the OBDII reader method and the car fails. Over the winter, I installed a full Z06 exhaust system.

I'm wondering if anyone has an opinion?

What happens to the IM tests ability to complete if I set P0141 and P0161 to "3" using HPtuners? ...

Thanks
EBoch
