Default 80D AI focus AF issue

I own a Canon 40D and 80D. the 40D I have been using for 10 years and the 80D two years. In terms of focus speed in all modes the 80D is way ahead of the 40D but in AI focus AF the 80D sucks in terms of responsiveness to changes in focus compared to the 40D. I have watched a good number of YouTube videos on how to set up the AI focus servo on the 80D but to no avail - my 40D runs rings around the 80D in terms off AI servo focus responsiveness.

Does anyone have a suggestion how to remedy this?

Sounds like you know what you are doing, so in that case (camera-error) a trip to a Canon service center might be the best advise.

Are you talking about AI Focus or AI Servo? I have never been happy with AI Focus on any of my cameras, so never use it. AI Servo with back button Focus works very well on my 70D and 6D. I don't have 80D, so maybe there is a difference.

Is there software that will show where the camera was actually focused?
NOT to be confused with software that shows which focal point in the camera was used.

Can I ask why you are using AI Focus? It is notorious for being a dogs breakfast of a mode. Part One Shot and part AI Servo with the camera trying to guess which mode you want.

Have you tried switching to AI Servo instead? Does that also perform poorly?
