If you don't mind the time and money for a dyno tune, the Power Commander V sounds like the best piggyback solution. It isn't as expensive as Buell Racing's programmable ECM even including tuning. It also offers the option of two maps and the ability to switch on the fly and a plug n play quickshifter. It may be the most attractive option to me only because the local dyno guys have no interest in messing with ECM mapping but they are all set up for the PC V.
In my neck of the woods, Northern Ohio Ducati will install the PC V, and fully map it, about 3 hours dyno time, for $250 flat. Three hours and done with measurable results. Sounds like a plan to me.
