Thanks for keeping the thread going a bit.
I emailed them as well, but I think it's probably hopeless. If they produce it, I'd probably be one of the first to buy, but I'm not holding my breath.
Unlike you e9x owners, I didn't have the option to get the N54 in my X3 and the new X3 was far from being unveiled... I need a S/C kit to avoid the headache of doing an N54 engine swap. Why do ECUs have to be so complex and highly secured these days?
