wbarnier, If the AIR your talking about is the SAI (air injection) then sure. Remove, plug holes and remap. You will need to disable the air injection in the map and save it. Then load it to the ECU. Disabling it in the fuel map only prevents the CEL, doesn't really shut the SAI off. You can reset the adaptations then or just let it adapt normally as long as your O2 sensors are still in place. Not really needed with this change I don't think but wouldn't hurt to take the steps.
