Problem with over or under extrusion on Creality Ender 3 V2

Please give some advise. I have done e step calibration, but it still over extrudes. I have reduced the flow and increased the flow but nothing help. I have a ender 3 v2. Everything is stock on printer.

I must have the same issue because my V2 NEO prints everything swollen. No fidgets or screw together containers ever fit. Always too tight.

UPDATE Problem solved…my bad!
An engineer who published on Thingiverse to a look at my prints of his objects, and noted that my x & y axis were sloppy. Tightened the belts and, voila! All good.
