I am trying to finish up the install I am doing on a 55 belair with a 05 4.8 in it. I need to make sure I change a couple things in the computer. I know were and how to just turn the vats off but what about the rear 02 sensors. I also am going to try to start it hopefully this weekend but will not have mass air flow sensor or air intake so I need to turn of the mass air flow sensor. Looking for some help to make sure that is not what is holding me up from being able to get it to start. The ecm is factory for this 05 4.8.
