Is there any benefit to having a Wideband O2 on each side of the exhaust? I have HP Tuners Pro, so I think it will take connections for two O2s.

I have true duals, no cats, and x-pipe.

Most people just use one. Take a stock 02 sensor out and use that bung. You'll be tuning in open loop anyway.

can't HP Tuners go closed loop with two widebands? I thought I read that somewhere.

I use the rear O2s on my Kooks X-Pipe on the passenger side. It's close to the X-pipe merge and allows for me to run the wideband up through the car. I figure it's in a pretty decent spot where it is. If you can do it with your x-pipe or y-pipe at the merge, that's a pretty solid place. Otherwise, the front O2s on either side would work (though passenger gets it closer to the laptop in my experience).

I have heard that the driver's side just after the header is the best place to add the wideband, leaving the stock front O2s in place. Just curious if anyone runs two widebands.
