Yes they can be scaled by pX_setunit(scale) function. I have tried this but cannot work out the correlation between the scale and the Ixx, Iyy and Izz values. I have tried an iterative process of manually setting the scale parameter then checking what values PhysX has, then adjusting the scale value again and then repeating this process in an attempt to get the correct values. With this method I could not get the correct Ixx etc values. Also this is not a practical solution.

Can anybody help please?
