I am installing arp studs and black onyx gaskets an egr delete and new oil cooler I also need injectors I was wondering if I could install performance injectors right now my truck is mostly stock all I have is a bully dog triple dog chip a air aid cold air intake and straight pipe any one have any suggestions I really don't have money at rebulid my transmission right now would injectors do me more good or more harm at the moment cause I really don't want a broke down truck or have to big of injectors

 

You can but.... you will need to ditch the bullydog. The bullydog with stock injectors is going to wreck your tranny faster than larger injectors with proper tuning. You will want to get an SCT and get custom tunes. You can get injectors then and have the fuel pulled back in the tuning until you can afford a larger turbo. 155s would be a good choice. You could put 190's in, but you wouldn't be able to tow very heavy without more air (bigger charger).

SCT and 155's would be your best bet IMO.

Also what's your budget... a new set of injectors is going to cost more than a transmission rebuild...

 

Well I have a little over 1500 at the moment the reason I am asking about the injectors is I think mine might be bad or that's what I have heard because when its cold sometimes it knocks real loud and I don't want to waste money buying stock injectors when later I know I want to put upgraded injectors

 

Well the thing is no one makes injectors for these. You can buy some "rebuilds" from some companies, but more times than not you're going to have more problems with them since they're essentially a used injector. The reputable shops have you buy new injectors from Ford, then send them off to get built to your specs. $1500 wont even get you a set of 8 from Ford, you're already way over budget on that unfortunately.

I'd spend the money on an SCT right now. That alone will be a nice improvement.

You can also try some Rev-X to get those injectors firing like new again. You'll be amazed at how well it works!

 

Alright that's what ill do then and has anyone taken the heads off themselves cause I have the injector rail off and I can't get the head off the braided line that comes off the injector rail to come out of the head anyone done this before

 

I'm pretty sure 03/04 trucks needed a special tool, but I think some have made their own. Might try searching for it. I haven't had this issue on the newer trucks I've worked on.

 

Thanks for Al the help it makes it a lot easier hopefully. Ill have my truck going soon I miss the black smoke

 

Try this.

You probably are done with this already, but I would check the FICM before worring about the injectors being bad. A half shell if its a 4 pin is only $400 shipped to you and it is just a bolt in. No tuning required.

If it is still running take it in and have a injector drop done on it and see how the injectors are running. I swore I had one going out, but after the tests I found the FICM to be bad.

Does it have the latest ford flash on it?

 

It'd be a lot easier and quicker to just test the FICM at home. Takes a buddy and about 10 minutes of time to do. That will tell him right there if it's bad or not. If it is, just solder it or find a buddy to do it, that's a lot cheaper than $400 too! It is interesting that you can order those half shells now through Ford!
