I posted the same question on the Innovate forum and here is the response from Klaus:
Nice car!! I know a lot of 930 owners have installed the sensor right into the muffler or right at the root of the tailpipe. The 4" between turbo and muffler are not enough. Also, because of the engine layout of the 930, there's not enough airflow over the sensor when installed between muffler and turbo and the sensor body gets heated beyond the Bosch specs of max ~550 degC.
