Accuracy of Autometer AFR Gauges

[Candy10]

I finally got this gauge installed and now that the numbers are in front of my face, I’m not sure if everything is as it should be. At idle, it’s reading 14.7 but jumps back and forth between that and low/mid 15s, kinda lean. At cruise (65-80mph), it’s the same thing except it’ll jump as high as 16, too lean right? At WOT its 11.3-11.5, not bad.
Waiting on my dyno day, where I’ll take the opportunity to compare the gauge numbers to the computer. But in the meantime, should i have concern? Are these numbers normal? Are these gauges accurate? Been driving on this tune for 3 years and 5500 miles, no issue. But like I said the numbers are right there in front of me now

It's going to move around a bit. Those numbers would not bother me.

I’m probably overthinking it. Lean is only really bad if it’s when on the throttle hard, right?

As long as there is no bucking or hesitation those numbers are fine for warm idle and cruise. Something between 11 and 12 is ideal for WOT.

From a tuner's perspective they are not great. AEM X Series is the standard. I had to abandon Autometer for wideband datalogging

Just did some searching, AEM is cheaper too. That’s just perfect lol.

If I change one gauge, gotta change em all though. Just not in the current budget
