Guys I've been wondering why there is so much fluctuation in my air fuel ratio so I decided to take a video of it in action. Thanks for the feedback.

Perfectly normal. The front 02 sensors will allow the A/F ratio to dither around stoich (14.63) in order to keep the cats healthy. Looks like your gauge is mounted post cat because it is showing between 14.7-15.1 ish. This would be because the A/F mix leans out through the cat. Even if it's not mounted post cat, it's fine. It's not unusual for wide band set ups to need a slight tweak in dead band in order to allow for voltage drops between the 02 sensor & gauge.

Again, everything looks to be working properly.

I'm not running any cats on my car. With this wideband, I had to cut a hole in my exhaust right after the collectors. I'm still about 6 inches from the collector.
I was just hoping that I didn't mount the sensor in the correct position in order to get an accurate reading.

Yah, OK. In either case, everything is good. At WOT, you should see her drop down to the 12.5-13.1 range.
