2000 ft would be compensated for with the altitude trim.

The issue with the post 851 bikes was that Ducati had some early issues with the reliability of the air pressure sensor, and rather than continue to risk a blown engine due to incorrect pressure trim, Ducati reduced the effective trim range of the pressure map, to allow SOME effective altitude trim, but not sufficient dwell reduction for greater elevations (which results in an overly rich mixture at high altitudes since they reduced the trim range)

This is easily corrected with something like TunerPro or other chip/ECU mapping systems, provided you are comfortable with the risk that a faulty pressure sensor could reduce the fuel by, say, 25% at sea level (incorrectly), and result in an overheated/blown motor.

I don't recall the effective altitude at whcih the mixture starts to become overly rich, but it's fairly easy to spot on the map.

Perhaps Brad/TomTom/Doug or someone else can chime in.
