No power/bad surge when cold

I have searched for a problem that mirrors mine, so if there's a thread out there that I haven't stumbled accross please don't roast me too bad...

I have an 04 F-250 that was built after 9/03. It had the casting sand in the cooling system issue, so I replaced the radiator, oil cooler, heater core, t-stat, water pump, and did the EGR delete. The turbo that is on there was a warranty replacement at one point in its life, but the truck had been sitting a while so I opened it up to clean the VGT.

The truck was a little cold-blooded to begin with and seemed to take a few minutes before it would be responsive. It didn't surge like it does now, probably because the VGT was rusty (there wasn't a whole lot of soot on the vanes). Even after it warms up and at a constant speed there is what sounds like the VGT vanes opening and closing at a fairly regular interval. I can also be sitting in park holding the truck at a steady 2000rpm and I get a whistle that sounds like the vanes opening and closing at a steady rate.

There are no codes and I don't want to send the local Ford dealership oweners kids through college by trying to figure this out. I did rob an ICP sensor off of a core 6.0 at the local salvage yard, no change. Any ideas on where to go from here ???

If I remember right they did reprogram the 03-04 for the vane sweep to try and keep them from sticking as much. Hard to say what you have going on but I know there was an update for the FICM to help with cold start issues but some guys dont like it due to the fact afterwards it seems to take FICMS out easier and people seen less power and MPGs afterwards. You could have some stiction going on and might wanna try some of that Rev-X

Rev-x saved me

New to the forum as far as posting. Typically I am searching for help for my 6.0 and I have found pretty much evrything that goes wrong with my truck are things that most owners here with similar milage have encountered and offered experience and opinions which truthfully has kept me on the road. For awhile I have been having similar rough running at morning startups and also at highway speeds, had to keep it up over 2000 rpms or it would buck and feel like it was missing. Already did head gaskets, injectors(8),new ficm with current flash, new oil cooler, egr cooler,egr valve, and every other gasket I could get to. It always came back to oil. I tried several different grades and the ford filters. Changing each grade only moved the rough running to a different temp range or rpm. I keep reading about Rev x and some say yes an some say bogus, but today I stopped at the local shop and put the 8 oz dose in at the parking lot and by the time I got to the main street she was running like perfect, I was at my wits end and needed to start moving trailers for work that I had been avoiding, now I feel like I have a truck again.

Got it figured out---VGT solenoid!!! I was able to snag the solenoid from the turbo core off of the same 6.0... They thought that it was gone, but it was hidden in between some transfer cases and transmissions on the shelf.
