View Full Version : Wideband tailpipe reading after cats ?

04-03-2007, 02:24 PM
I wanted to check wideband afr in my 96z and its got cats and don't want to make another bung.
Is this going to work at all. I have heard it does work just might be off .1 or something so 13.5 might be 13.6 type of thing. Don't most dynos still check afr with tailpipe reading?
