As I mentioned earlier, only DMS has a remap for the 3.0 ltr in Australia - they cracked the encryption some time ago. There are a few others that claim they can do it, but no product for sale as yet.
All the 2.7's use the same hardware/firmware, so remapping a 2.7 D4 is pretty much the same as a 2.7 D3.
Cheers,
