Can anyone confirm that an SCT Tuner will let you "turn off" the rear O2 sensors? I talked to a rep. from SCT and he told me that option was a standard thing on their tuners.
Thanks!!
Thanks!!

I had mine turned off on my custom tunes. I can mess with it later and see if it's an option. I'm pretty sure it is. Still passes emissions test with them off as well. I have the X4. Much larger and nicer screen.
