Tach ticking motion

[Syracuse Supra]

My tach is making a ticking motion at idle and when car is off. Any idea why this would do that? I recently flashed my car to an updated map, but not sure if it is that or something completely different.

I'm not sure what tune you have but if you go back to your old tune or stock does it do it?

Went back to the previous flash and it looks like the issue went away. The new flash did have an e50 tune as one of the maps where it didnt in the past. Maybe that has something to do with it?
