I am thinking about getting the prochamber. My only obstacle is going to be being able to pass emissions in Massachusetts. I have heard that the MIL eliminators ONLY turn off the check engine light (if they work at all) and that I would need to purchase a handheld tuner to eliminate the rear 02 sensors during inspection. Is this all true?
