Rob all you can do is read withthe OBD2 or as I call it the OBGYN plug

You need Tune Boy or the other brand tune ecu. Tune Boy is pricey but they are more advanced when it comes to modifying maps. They were the ground breakers on the Rocket and many other brands.
Of couse not to sound smart assed but since you have a 2011 I would put some miles on her and get used to throwing it around with the power it has (which is plenty) then after a while you can start modifying her. Just a suggestion as it was made to me when I bought my 06 Classic. I put 22,000 miles on with just Tors and cat delete what a blast never did anything but check and change the oil and brake pads, oh and tires.
The Roadster is new and you will see a lot of goddies get developed for her over the next couple years.
