i,ve spoke with about 10 mechanics, they told me the best way is to disconnect the after kat o2 sensors.
but that will cause CHECK engine contol unit. Now i want to disable that
Predator won't disable rear O2 sensors? (Moved) - Chrysler 300C Forum: 300C & SRT8 Forums

Pick up a diablo predator and put old software on it. You can turn them off with that.

My Station Wagon was faster...
last i checked, turning them off with a handheld tuner will only turn the light out. a full tune with them disabled is what is needed. If only the light is off, you will still fail a computer emission state check.
