if you go bigger injectors, and twins you a deffinately going to raise pressure, i would suggest you start with simple things as stated above, and make sure like he said get a new fuel feed, airdog, fass, etc. you will also need to replace your headgasket, and stud the engine, the stock rods wont hold all the pressure, and will blow. and thats no fun. also make sure you deffinately have gauges, they are of the upmost importance on a truck. fuel pressure, exhaust temp, trans temp, rail pressure, and boost are the main ones, depending on your goals, you are probably going to have to upgrade your injection pump also, to keep up with your injectors, and fuel supply, cause you can kill one in a hurry. i think in my opinion the arson cp3 is a great addition. you can try dual feed on your cp3, but you have no return line then. bbram has the dual feed on his 03 and so far so good, he would be the man to ask on that one. and also like stated before, it will be hard to stack the banks, go with something like the smarty sr. you can adjust it to where it adds fuel only, no timing so you can stack with a timing box, and make some great numbers. alot have stacked it with edge boxes, and made powerful numbers. did i leave anything off fellas?
