First thing I would do is check to make sure it’s not a sensor problem... that seems crazy jumpy. I have the same gauge and it does not bounce all over the place like that

theres actually a way to check if its reading properly. forgot to mention on my first post. but if remove the wideband sensor from the exhaust, turn the key to the on position, take a rag and spray brake cleaner on it... and cover the tip of the sensor with the rag it should make your gauge peg rich. When I first got my aem uego i was running into an issue right out of the box, and that test helped me verify a bad sensor and once i replaced it, everything worked fine

just make sure you buy a bosch LSU sensor and not some ebay crap. AEM are bosch sensors, just rebranded and marked up 300%

I did the test and it still show full lean. I'm going to replace with Bosch 17014. Is that right?
