Air fuel ratio video

[Interceptor]

Stock ecoboost, charge pipes and cold air only. Not a mechanic, doesn't look good to drop so much under full acceleration?
Is this how it should look?

Video won't load, says too large. At idle needle bounces slightly on both sides of 14
Under full acceleration it drops below 14 and drops and drops all the way to 10 on bottom side
Gonna work on getting a video.

That's utterly and completely normal on the stock calibration.

Thanks, never looked at that gauge and I was ready to get on my 36,000 mile mark.
