Known Issue - to IAC or not to IAC

[BlackDenis]

 :oThe contributers in the forum linked to in the IAC sdction suggest that doing the IAC is a good idea to maximize throttle body settings: get  98% as opposed to 90% (whatever that means). But, the Known Issues link says that on the twin cam 1200 you should also visit BMW for an ECU reset... and send data to HEX.

So, better to wait until this is resolved? I bought the 911 to avoid the dealer/expense.
