Brakes went out
Similar thing happened to me. When I first built my sideways intake mani the progressive linkage on the TB hit something and got jammed wide open. shutting the car off while it's bouncing off the rev limiter made the tach go the wrong way and zero out pointing down. Like you I had to take the cluster apart adn spin the needle around.
No cops though.

Wondering if your tach looked like the following before I disassemble mine and reposition the needle. Only recent mod is COPS but I took apart the ignitor, to verify the white tach wire was still connected and it is.
EDIT : Tach works in tunerstudio
Car off / key out of ignition

Car off / key in ignition in acc on position

Thanks, spun tach needle counter clockwise and problem solved... temporarily. The tach needle spiked 0 to 7k again this morning as I went to start the car (acc on position) but thankfully it went back to 0. Something screwy is going on with my COPs that im yet to figure out.
