How to transfer boost UI (PSI) to another car?

Once i do transfer the UI (the whole frame with speedometer, bln, other stuff) and values it needed, the gauge doesn't work on the car i did transfer to, tho the car i did it from works perfectly fine. How do i fix it?

just put the gui inside each car model. And for the values, put them in a folder that can be accessed by any of the guis
