oxygen sensor heater codes

[383ls6]

since installing my new engine I've been getting p0135,p0155 codes. The circuit tests fine I'm assuming it's because of the cam. MY question is can the heaters be turned off via tuning without any adverse effects? As always any advice is greatly appreciated.

you can turn off just those codes......how old are your sensors? If you have headers that's most likely the reason for the heater codes. I solved my heater code issue by using bosch 13111 sensors. Had those in a few years now and haven't had a single heater code since installing them.
