it says when you do a ecm upgrade that you need to have someone re calibrate you throttle position sensor....Can this be done by myself or do i need to take it to a shop?...What is involved in doing it and how much would it cost to get done?...thanks, Mike

Unless you have the Buell DirectLink system, you need to take it to a dealer. It is part of some of the required services, but otherwise is about half an hour of labor, usually around $35 or so.
