5.9 Blub-Blub

Hey all I'm new to this whole Forum thing. Yesterday was my 22nd b-day and I'm debating on what to get for my truck. I was thinking about higher hp sticks but then I started to think about a new turbo because of the current mods I have and because I don't know how high of hp sticks I could run on a stock turbo. So I'll tell you guys my current set up and hopefully someone can help me pick between a new turbo or injectors. Also this is going to be bought by the parents for my B-Day but I'm not trying to be selfish and get something super expensive. Thanks for the help Guys!!
