Reverse gear shift pattern and I think maybe softer cams or slightly differant gear ratios ....but then I could bee wrong about the last two.
Not sure how true but I am sure I recall reading if you put the Mille gears on the falco it gives you race gearing
different limit to max throttle body size I think and again I think the falco was the base used for the tuono
Another Falco/Mille question.
Can you run a falco engine with a Titanium ecu chip?
