The gauge might be the one more accurate, since it's not dealing with a ground offset.
The only way to know for sure is to connect to the wideband with the serial connection (no ground offsets) and get the data that way.

We got this guy Not Sure, ...
Keith is right.. it could be either one. On mine I assume the gauge is right but it uses a serial connection so that's a little easier to be sure of
In reality you're talking about ~2%, so it's close regardless. If you want to go through setting up a custom input so you can adjust the reading a little bit let us know and I'll try to walk you through it.
