Default Throttle position sensor adjustment?

According to the VSDST software from technoresearc, my tps only registers 59.7 degrees at WOT, 4.1 degrees at closed(idle).

Is this adjustable or is my tps bad and need replacement?

After moving around and pushing the connectors for the tps and the ecu tps readings are now normal, 5.7 deg to 83.4 deg at WOT.

I used a cheap multi-meter and measured resistance. The tps is setup to deliver a voltage to the ecu, the potentiometer is supplied +5v and gnd, and center output is the metering circuit.

The resistance between gnd and output is 1.35 kOhms at idle, and 2.15 kOhms at wot
