Been scanning my ‘11 CTS V and saw high IATs on the gauge in the display - 125+ consistently. Tuner thought my innercooler pump went bad so I replaced it and now the gauge fluctuates from 100 to 120 but in the left hand column it showed 100-102 degrees. Not sure what?s going on but I also noticed that my oil temp is showing -40F.
Am I going insane or is there something wrong?
