Hey Stew,
My advice on the pc111 is to find an authorised installer and dyno shop ( Woodies Motorcycles Tuggerah for exmple ) If they install it and anything goes wrong with the bike or pc111 they are liable. It is very easy to set the wrong maps for your bike if your only using generic ones, get it on the dyno and you will be amazed at the difference. I would see if your shop will dyno it for you before the air kit then with it then with the pc111 and a custom map that way you can see real differences
