Hey everyone. While looking through the torque app I stumbled upon the catalyst temps for my 2011 Tahoe with 5.3. Bank 1 and bank 2 are reading 990 degrees fahrenheit. Does any one know the normal temp for this? Those numbers seem really high. I have no check engine light and seems to be running fine. Thanks for the help.
