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.

5K return ah? supercharger it!!

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

but my truck has 260 at the flywheel already + the bolt ons....

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

it's a 2000 2v....

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.

yeah what he said^ get a 90mm lightning MAF
