Mazda6 MPS remapping?

Hi all, I'm hopeing someone more knowledgeable than me will be able to tell me where I can find someone to remap my MPS. So far numerous googles and telephone calls have led to the general comment "it's a new car, someone will do it soon".
It goes well as it is but 300+ bhp would be nice!!!!
Awaiting someone to help me!
regards
Mark
