They probably didn't redo the speedo dots which, by the way, indicate the max speed at which you can manually downshift, not the max speed for the gear. Pedal to the kickdown switch, the SDL speedo pointer will swing past the dots. An Italian tune-up of the SDL includes doing over 80mph in 3rd. Or so I've heard The 3 dots are at 80mph.
