Ya misunderstood... Since you got an '09, your stock ECM may be able to remap itself (in 15 minutes they say) to your new pipes and air cleaner. No need for a new ECM or having somebody remap anything. The stock ECM has a lot of play area for changes without having to be upgraded. I believe I read this in American Iron.
Personal experience? Nope... I got a carb. But I'd try out leaving the stock ECM in and riding it for a while to see what happens. Maybe do a plug chop to see if you're on the lean or rich side.
