where is the best place to put wideband bung to get best reading?????before or after o2 bung an should i put 2 in??????

 

IMO I would say before the cat because I would want the exhaust to be the un tampered with. I use just one. I know that you could probably get better readings from 2 but it seems like to me that there isnt much difference between the 2 sides of the motor and if there is then you have issues elsewhere.

 

My ARH's came with the extra bung and it's on the driver side, almost directly across from the O2 bung.

 

Depends on your exhaust set-up I think. I was running LTs and true duals and now LTs and ORY(no cats), both times I located the bung basically under the driver's seat before or as the pipe makes its first curve towards the center of the car. Make sure the bung is level, you don't want your sensor hitting the floorboard or dragging the ground.

 

k very helpful info... thanks u guys for the help
