you can do a few things to over ride the system... you can turn off your rear O2 sensors but if they plug in they might be able to tell... you need to ask him to what extent the computer checks
well if all they do is plug in and check to make sure that its getting a reading you might be able to MIL it and get away with it... if you turn off the rear O2's that might trip there system and fail you
