whats the stock fuel system good for?

I was wondering what the stock fuel system on these trucks is good for in terms of HP. I am getting near full bolt on's with. Intake, exhaust, efans, and troyer tunes. The cats will be coming off and UDP's most likely by christmas. I will be wanting more and will be hopefully puting on a 75 shot of nitrous come income tax time. (I am looking at a 5k return!) So basically what I am wondering is what the MAF, Injectors, and fuel pump are good to as I would like to start shopping for some of these parts now. If I need 24lb injectors or larger I would like to start shopping for them now, same for the MAF and fuel pump.

a 75 shot wont require more fuel. you can go to about 300hp flywheel before upgrading anything

Aren't the 5.4's rated for 300 at the flywheel, and the parasitic loss is through driveshaft and rear axle?

You need to upgrade at 300-310 flywheel HP. Upgrade to a 190LPH fuel pump like Walboro. Get 24LB injectors and i'm not sure the size of the MAF you would need?? I think Troyer lists a fuel system upgrade on his site somewhere in one of the packages. Don't forget when you upgrade injectors you need another tune.
