There should be some sort of math looking problem at the bottom of the wideband pid, the place where you can edit the name and the function.
I don't recall for all widebands but the math problem likely ends in a (/10) for something like that, you can change that to 9.8 or 9.7 to make the wideband closer to what you see in the gauge.
Hopefully you can understand what I'm saying here without pictures.
also..ensure you use the same ground/power for all the gauges. That might throw them off slightly.
