I'd ask Mazda about how they do carbon clean. My service department uses one that runs through the fuel system and out the injectors. The theory behind it is that it will spray onto the back of the valves and clean them. As the MPS has direct injection, it will just be spraying it straight into the combustion chamber and will have little to no effect on carbon build up on the valves.

I have used a product from Nulon called Foaming Air Intake Cleaner (supposedly similar to Subaru Upper Engine Cleaner, which I'll be trying next). It didn't make much difference to me but I haven't taken the manifold off to check.
