Can I revert to stock tune but still manage to turn off rear O2 sensors and set my gear ratio to correct speedo? If so, how?

If it hasn't been updated yes you can turn off the o2. And yeah if it's post 99 same thing for speedo

I believe he covered your question good. I get his answer. The way i understand this is, you want to return the tune back to stock and still have the adjustable options capabilities of the tuner?

That is correct. Stock tune, modified for gears and no cats

Yeah you can do that. The update I was referring to is the hand held being updated. I made that mistake and that o2 option is now gone. Should be able to modify the stock tune any way you like
