Try a search for "08 self mapping" or "no mapping required" This has been debated all year whether the 08 needs some kind of additional fuel management or not. Some tuners say that if you add a full exhaust and filter that the stock computer will be able to adjust enough from the 02 sensor readings and will be fine and that the PCIII would only be necessary for a heavily modded bike. Others say that the bike will just run "OK" on the stock ECU and if you want "top notch""most you can get from your bike" performance then you need a PCII or Bazzas and a custom tune. Do some more research here using the search feature and decide for yourself.
Good luck and enjoy the new bike.
