[Ducati] 1999 996S question

[Veloce916 at aol.com]

Just got this question from a friend regarding a 1999 996S.  He's  trying to 
determine what that model year offered and has been given conflicting  
information.  The question is:
 some information states that these motorcycles had the SPS cams and  high 
comp pistons @ 123hp other info states that the motor is the same as a 996  only 
with big term exhaust and a chip.
 
 

Anybody know for certain?
