Im in the same basket (except in Australia). So far i can work out that depending on the year the throttle bodies may or may not be restricted (smaller hole than the trumpet size), the computer restricts the TPS vs throttle opening and doesnt do the engine any favours on timing and fuel delivery.

Most people are following the normal path, intake (air cleaner), exhaust (your choice) and computer piggy back (power commander...)

I havent done any of the above yet but will be in the coming months.

Could be air+ecu restriction, could also be a throttle-stop restrictor.

Ask the dealer you bought it from would be my advice. Did they not supply any de-restricting documentation with the bike?
