For whatever reason, the WG Duty goes to 100% immediately and then the throttle closes (screen shots attached). Maybe it is also some sort of a defective contact? I don't think it is a mechanical issue otherwise it would have done it all the time - besides, the software appears to be giving a false command anyway.
Any ideas?

Closing the throttle to about 20% is ecutek inbuilt overboost protection in Radeon 10 and above.
I'd check you MAP sensor is ok, then can fail and read incorrect boost levels.
Also your waste gate actuator may be stuck or the boost line leaking or blocked
