Help setting up

I have a 2003 chevy silverado 1500 Z71 with the 5.3 327.with 3.73 rear.
I have added a Gibson stainless steel 2.5 cat back duel exhaust, Volant cool air intake mass air flow sensor, Throttle body spacer and have the Hypertech3 programmer. I am a little disappointed with the increase of power it is putting out. I don't know if I missed some thing in the set up of the programer or what. If you could please help me with the optimal settings for the programmer I would really apprieciate it. Maybe I was expecting to much.
