I don't want to relocate the bungs on my obd1 header. Is there any performance loss, pros or cons to doing this? The Ecu should then use that one o2 reading for all 4 cylinders... correct? I would assume so, but I just want to make sure.

Also, what ECU chippers do you all recommend?

Come on now guys, plug your favorite shop.... I have no idea who to use here. I'm in New Mexico...... maybe inline4 or Jdmhondaparts??????
