Throwing codes p2270 and p2272 bank 1&2 sensor 2 stuck lean.
My tune is adjusted for off-road according to an email I have saved stating it is when I asked if it was.
They are not hooked up, but to my knowledge if they are turned off (just the rear o2's), they do not need to be hooked up. Can I get a confirmation on this? Maybe the tune does not really have them turned off? I still have the email conversations and the tune saved in email.

Any help is appreciated, thanks.

Also, instead of making a whole new thread I'll just ask this in here.
I am having gears installed soon, also maybe an egr delete. Do I need to get a new custom tune or can I have my old one adjusted?

got O2 extension harnesses plugged in?

The rears are disconnected. They have to be connected even though they're turned off? I read up they didn't have to be.
Thanks for the fast reply.

Guess I was misinformed. Thanks for the information, I'll have them plugged in tomorrow and report back. Hopefully all is well.

Now for my second question? Thank you.

Well I fiddled with my tuner and I figured out I can change gear ratios myself. Do I have to change anything else like tire size or should gear ratio alone be fine?
This will end my questions, thanks.
