02 sensor issue
 

I have a 2011 SS that has a Maggie SC, headers, and hi-flo Cats and ZL1 exhaust. A few days ago while driving, all of a sudden the car hesitated and then a message appeared that said reduce engine power. I checked the code and the P0050 H02S Heater Circuit Bank 2 Sensor 1 appeared and something that mentioned throttle body. In reading a few other postings I see where some are saying this should have been tuned out. I have driving the card for about 5000 miles since the tune so I am not sure if thats the issue. A few other codes that were found were P0116 and P0155. Any help will be appreciated.

Its been a while but I think you are right. bank 1&2 sensor 1 should be turned off/tuned out.
