What are the actual differences between a plain sp800 and the 800H.O.'s? Is it just different mapping in the ecu or larger cam or???

as far as i know and can remember the H.O. of course stands for high output and is basically a different cam. although, now everything that comes to the US should all be HO.....a couple years ago that always wasnt the case though....if memory serves me right

Do you recall about what year that changed? I just bought a 2007 and am curious about the status of mine.
