Anybody know any special tricks/procedures for adjusting the throttle position sensor on an M30?

This procedure is for a VG30DE. I know the M30 has a VG engine. Hope this helps:

Setting the Throttle Position Sensor Install throttle position sensor in throttle chamber but do not tighten bolts. Connect throttle position sensor and idle switch harness connector. Start engine and warm it to operating temperature. Leaving harness connected, measure voltage by inserting voltemeter probes through the back side of the harness into terminals [a] and on the sensor side. Adjust sensor by rotating throttle sensor until output voltage reads 0.4 to 0.5 volts. Once correct voltage is reached, tighten mounting bolts.

Every car that has a TPS gets set more or less the same way.

There are SAE STANDARDS for engine sensors.
