tuning O2 sensors So I have a 99 T/A that is your average bolt on HCI 6spd car. I bought the car as is and have done nothing to it in the past few years that I have owned it except for add a racetronix fuel pump and a general maintenance. The previous owners who did all of the work had the car tuned a few times and it made around 430rwhp.
I was always under the impression that when a car is modded like this that the O2 sensors are usually taken out of the equation in the tune. However I have recently had the check engine light come on a few times, and it seems to be caused by the O2 sensors.
So should I just replace the sensors? Or should the sensors be deactivated in the tune?

it really depends on how the car's set up. however what's important here is which O2 sensor went bad, the pre-cat or post-cat? the post-cat O2 sensors is aminly for emissions and ppl generally turn those off. the front ones are the ones that are important and the pcm goes to determine how much fuel is burnt up and adjusts the air-fuel ratio (AFR).

Here is a classified add for the car from a previous owner.
If you scroll down a few pics you can see that the car only has one of the rear sensors and the other is plugged. Any reason for this?

Is it only throwing a code for 1 sensor, switch them to make sure the 02 is really bad and it's not something else, I've run into a problem where my PCM isn't even reading o2 bank 1 and running lean
