Ok....so I have no clue what type of injectors my truck has. Its an 07 5.4 3v. I have 39#'ers right now, but after I get the new rotating assembly put in my truck this month, I'm going to need to upgrade them so I can up my boost. I'm going to need between 50 and 60 pounders. Can anybody tell my the specific type my truck uses so I can google some stuff?

 

here you go bro.

I'm just going to go with some 55# injectors off a gt500...and its fuel pump. 20 psi here I come!

 

I been talking to a guy on svtperformance and he made 500hp in a L with 42lb injectors. Just a thought.

 

sounds like a plan if you can get them cheap.

 

cheapest I have seen on 60lb pencil injectors for our trucks

Any Bosch EV-6 type injector will work but don't go too big without need. Big injectors get harder to control under idle and low-load conditions. They don't atomize the fuel as well at low duty cycles either. I would stay away from anything other than OEM injectors though, Ford uses Bosch and they are top quality. Siemens are good too. The GT500's injectors would be a good bet and have plenty of flow.

 

Thanks guys. I'm going with the Gt500's. Getting them for cHeAp
