The hp bump is small but, the real difference is the variocam change. The 03 had continuosly variable valve timing where as the pre-03's had a selonoid that basically was an on-off switch. Jim made a great analogy regarding this once, he said one is like a adjustable light switch that can be gradually adjusted and the other is like standard switch that is either on or off. The improved variocam design allowed for a better torque curve and fuel economy.
