I have a buddy that has a 2012 FB6 fully bolted on and went to get smog tested. He found out that the second O2 sensor was not working. What i mean is that is was turned off after modification through the tuner. My question is can he turn it back on to get tested? When he got it tested they said they couldn't becasue of the second O2 sensor. Has anyone with dp and tune been smog tested? Also what would be the ill effects if he turned it back on through FP?
