Valve connector detaching with desired pressure:

When you detach the valve connector, the tire valve would keep releasing air until the connector is fully detached. It's normal and can be accepted by setting up desired psi value on the machine. For example when you set 32 psi, the machine will keep pumping to 32.5 psi before it stops which consider the loss will be happening when you detach the valve connector.
