Anyone have an Autometer Wideband A/F Gauge?

[kkdoughboy]

I installed an Autometer Cobalt Wideband A/F gauge in my 07 GT 5spd. The car has the mods listed in my signature, NA. I'm getting readings of around 14.5-15.0 when driving the car. I had the car dyno'd on a dynojet and the A/F was around 13.0 the entire rpm band. I'm confused as to why these numbers are differing so much. Do I have to calibrate the Autometer gauge to 13.0 and work from there? The set point for the gauge out of the box is 14.5. How can I get an accurate reading? Thanks

It still reads at around 14.5-15.0 at WOT.

Is the gauge/sensor new or did you buy them used?

It was a brand new gauge. I took it out for a test run and the numbers do drop at WOT. From like 14.5/14.7 to 13.4/13.9 range. The numbers are all over the place though versus the dyno which read a constant 13.0 through redline. This thing jumps all over the place and its impossible to get an accurate reading. I bought this gauge to monitor the A/F while using my Nitrous but it being so accurate isnt gonna help me at all. ?
