NEED HELP narrowband air fuel mixture gauge going nuts

[tunerdoc]

Help I have just installed two Auto meter gauges one Boost the other air fuel. The boost runs in the vacuum until turbo kicks and then heads for 11 lbs. The air fuel goes back and forth rapidly, under boost it goes to rich then goes nuts again??? I want to put aMBV on but not till I can get a handle on this so I have safe perameters.

Can I get help?
Is it a bad gauge?
Ground?

It is tied into the ECU for info

Thanks
Doc

hey if you read your intstructions for the gauge it will tell you that it does this that is why these gauges are not reliable they only work at wot
i have a 1g and it does the same thing so does my dads 3g that is why the next gauge im getting is the egt that is way more reliable
