P3106 Code. What is it?

As the title said I am pulling a P3106 code and I have no idea what it might be. I do not have a cat but the JB4 said it is a inefficiency code. I did a little searching and found different things

This thread said it was an O2 sensor.

This says its a faulty injector.

Any thoughts on what it might be?

Just an FYI. I asked what P3106 was in the Cobb thread and got the following response from Cobb:

"Those are both codes for Catalyst efficiency (just reported in 2 different ways). If you're running a catless DP with anything less than Stage2, you will get these codes.

-Josh"

Seems normal according to the Cobb dudes....just another way of reporting a cat efficiency. Take some logs to verify it's all good and call it a day.

Yes. Like I said run some logs, verify the car is operating correctly, and then mask it.
