Hello All,
I got a 06 TBSS and I am at that time to plug in a new tune. I was thinking of disabling the rear two oxygen sensors, so I can plug in my AFR gauge I'm adding...has anyone done this and what are the pros and cons to this???

There are no cons if you disable the COT and the post cat o2 sensor test/codes. On some vehicles unplugging the sensors will trip a cat diag test that you can not shut off, so just zip tie the sensors out of the way and leave them plugged in.
If you are still running cats, you wouldn't want to put the wideband behind the cat. I wouldn't want to anyway.

If you don't post your tune and logs when you have questions you aren't helping yourself.
^^^ um no.....
Just remove them

Appreciate the response fellas...
As a matter of curiosity, have you tried replacing the sensors with an o2 sim?

No I haven't...
I didn't try that and I sold my old truck a few years back as well.
To me it would have cost more money and not been worth it to try, it's easy enough to just zip-tie the sensors out of the way.

Fair enough. Ill be trying it with a sim here shortly on my Z as I'm going to temporarily borrow one of the rear o2 bungs for a wideband.
Im aware of the impact a cat will have on the WB, but for my purposes (ensuring theres nothing grossly out of line) the offset isnt a bother to me.
