is it a full race system or std akra twin set up with removable baffles?, have you modded the airbox or anything else yet?
If you fit a PC111, a custom map is deffo recommended, they can really come into their own then and you can even mess about with 'open chips'(see Ducati-kaemna.com) and get big power increases.(if thats what yer after) in my experience I got better low rev-low gear response withmore urgency all over the range and a few ponies on top.
But only worth while really once you start tunning her with lots gofaster bits!... unles you think the fueling at the mo is jerky, or you can feel dips in the powwer at certain revs and you are not happy with it
