Factory Boost Gauge 06 F 350

So I was noticing that it will go up to about the line after the 20lbs. After it sits at WOT for a second or so, it look as if it goes lowers. Is this a normal trait of the motor or gauge?

Yeah. As the RPM goes up, the amount of cubic feet per minute required goes up also. As the demand goes up, the pressure drops.
