Good luck with that; the Boxster uses one of the ABS/PSM wheel speed sensors to determine ground speed, and the instrument cluster gets that information from the DME. Considering Porsches penchant for incomprehensible logic in the DME software, you would need to reprogram the DME, which is anything but easy, even with a PIWIS. And the government gave automakers considerable leeway on instrument cluster accuracy a long time ago, which is why these cars have idiot lights that move instead of real instruments.
