The difference in sound could be something as little as how high/low the idle is programmed. I'd suggest searching and doing the research on the various cams and coming up with the best one for you. If this isn't a DD and you want that kind of power, likely I'd think you want a bigger cam like the IS3/IS4 or XPZ
