so im hopefully installing my borla exhaust tmmw and then i should have a full bolt on car (headers, catback, intake, etc).

so i just got a quick question. where will my tuner hookup the wideband o2 sensor? does it need its own bung or does it just get swapped with one of the stock o2's? im currently running a tsp catted y pipe; it only has bungs for the front o2's, no bungs for rear o2's.

 

They will just put a sampling wand in the back.

It will give you an accurate enough reading of your a/f
