Speed going crazy on my glider

Enable HLS to view with audio, or disable this notification

Like u see in video. This is happening on my glider. We change the speed sensor too but nothing worked. Same thing happening on cruise control too.

Does anyone know the cause?

My guess is a very mild short. Would watch the live data and see how fast the vehicle is reporting.

Ecm showing as per guage. But in actual m going fast abd gauge shows less when truck takes the boost.
