Oxygen sensor placement
I am installing an STS setup. I am not sure about the proper placement of the oxygen sensor for measuring the air/fuel ratio. The instructions for the gage state to put it post turbo but before cats. With an STS system obviously this cannot be done. Which would be better (1) pre-cat but before turbo or (2) post cat and post turbo.
Any guidance would be greatly appreciated. I am getting ready to weld the bung on the exhaust and I don't want to do the job twice.
