The Kalgooorlie Toyota dealer used to do it for us when it was in for servicing and it always made quite a dramatic improvement in performance. I believe they use ammonia somehow, to dissolve the carbon deposits. I know that supermarket cloudy ammonia works well on wood stove glass windows, but how the process is actually done in a car engine, I have no idea.
I found a video of a Suzuki Vitara being decarbonised, but don't know what the stuff is that it says they're using: ProfessoR (xpress decarbonizer) from Oilyman Technology. (This process is not for the environmentally sensitive - it looks dreadful!):
