2005 6.0 Powerstroke Injector Help?

Okay so I have a 2005 F-250 6.0 Powerstroke which has 275,XXX miles on it. Been a work truck all its life. No rust on it at all but has a few small dings in it. Paid 3500 for it so can't complain. But anyways, I have replaced many things on it. Installed an EGR Delete Kit (cleaned the turbo while I had it off), New water pump, New thermostat, new radiator, and a new FICM. It was overheating but I think I fixed that problem. But now I have a new problem. It runs really really rough until it gets warmed up. Once warm it runs like a raped ape. It just shakes, has a loss of power and wont shift correctly. I took it to a ford garage for a diagnostics test and they said injector numbers 1,3,and 4 need replaced. Now I have a hard time believing that because it runs like a new truck when its warm. Now I seem to think its the injector spool valves but ford says its just the injectors. What can I do to solve this problem instead of having ford replace 3 injectors for 1500$???

Try running some rev-x thru it it may be striction causeing sluggish response of those injectors.Be shure your oil is fresh and clean and you are useing Ford/Motorcraft filters.

I change it every 3000 and i use "Hot shot's secret" which is an oil additive sold by international garages which is supposed to help with stiction. Im completely out of things to do to it besides change injectors

it really isnt the faulty injectors actually they have a very good design but it is instead the dirty diesel we have on the U.S...i always run a bottle of lucas additive on each full tank and rev X every oil change and since then my injectors work as they should...although if i had the money for bigger injectors i would do it for the power gain lol

I going to agree with the dealer diagnosis on this one, based on the information posted. Unfortunately, mechanically weak/faulty injector(s) on these engines can only be pinpointed during cold soak exactly as you've described. As far as brand of injectors, either go with Ford/Motorcraft/Navistar or Alliant. Any other "white box" no name brands and you'll be doing the same job over again very shortly on YOUR dime. As far as why you refuse to accept the injectors needing replacement? Really? This truck has 275,000 miles on it. If all eight of those are in fact original, count your blessings.
