How Can I Get More Power Out Of My 05′ Chevy 2500 HD 6.0L V8

I am trying to find ways to get more power. I have a cold air intake and a duel free flow exhaust system with NO headers.
My question is if a MSD system or headers will help? Also, how about a power programmer? Hypertech has that new Max Energy system, will that help? I have also seen a turbo charger for my model by Synergy Motosports that looks good but is pretty pricey. Any ideas anyone? What would you do? No one line answers please, I am actually trying to learn something here… Thank you for any help you can provide.
