Good question I've never thought about that one. I believe that Stage 2 removes both the Up Pipe CEL and I know for sure the Down pipe CEL. You could leave it in and it wouldn't hurt any thing or you could take 5 min and test it out. If it throws a CEL use the AP and clear your DTC and then throw back in the resistor.

According to map notes for the Stg 2 V1.22 and Stg. 1 V1.20 it is one of the CEL's that is deleted already, so you shouldn't have any problems:

(** means new to latest revision):
P0037 - Rear O2 Sensor Heater Control Circuit Low **
P0038 - Rear 02 Sensor Heater Control Circuit High **
P0137 - Rear O2 Sensor Low Voltage **
P0138 - Rear O2 Sensor High Voltage **
P0139 - Rear O2 Sensor Circuit Slow Response **
P0420 - Catalyst System Efficiency Below Threshold
P0545 - Exhaust Gas Temperature Sensor Circuit Low
P0546 - Exhaust Gas Temperature Sensor Circuit High
P1301 - Misfire Detected (High Temperature Exhaust Gas) **
P1312 - Exhaust Gas Temperature Sensor Malfunction **
P1544 - Exhaust Gas Temperature Too High **
