How much hp can stock fuel system support?

[paradiserfd815]

I'm wondering if I should go to airdogII. ARP studs, egr delete, 4" mbrp, 58v custom ficm, sct with custom tunes, coolant filter, ccv delete, royal purple 15w40. If my stock system is adequate I hate to spend the money on airdog when I could use it on another upgrade.

Do you have a fuel gauge?

i dont really think you need to get that hot of a ficm if your not runnin uprgraded injectors

your factory fuel will support a custom program, but it would not be a bad idea to get a regulated fuel return. but for the price of that you might just want a airdogII. your going to notice that these trucks cost alot to upgrade! lol

[TNStroKE]

very true hope you have deep pockets

I have pillar fuel gauge, pyro and boost. Is factory system sufficient or would airdog II make my setup better?

Depends on the many ways to tune the truck.
And the fuel flow; bigger fuel lines, fuel banjos, pressure.
Along with the air flow restrictions; intake filter, turbo, boost tubes, inter-cooler, intake manifold(gogodiesel), exhaust.

The stock system can even support 155cc inj, if it can, some stock fuel systems are not able to because of age, maintenance, fuel restrictions.

If the stock fuel system was worked(list above) on to eliminate flow restrictions, it can do very well with HP numbers.

yes there are plenty of people that run with the factory fuel system. an airdog will help you out better under wide open throttle. an airdog will make sure u have good fuel pressure all the way through. which intern may make your injectors last longer. i suggest doing some reading on 6.0 section.

Wot is where I'm wondering if I'm getting sufficient fuel. Don't want to mess up injectors.

[scotty2280]

you will need a fuel pressure gauge for that.
