2006 F-250 loss of power /rough idle NEW FICM JUST INSTALLED

Hey guys i just bought a 2006 F-250 6.0 powerstroke with 82k on it. The truck has been sitting for 2 years not running. I had it towed to the shop and the FICM was bad in the truck. I got a new one from the ford dealership they put it in and reprogrammed it. The truck runs now but at low rpm's and at idle it runs rough. It feels and sounds like the truck has a "misfire". It is definatly under powered. Im a duramax guy through and through but i went against my will and bought this 6.0 lol. Not sure if i have an injector issue, egr issue or whats going on. I changed the oil in it with motorcraft oil along with the filter. I also changed both fuel filters on it. The truck had 1/4 tank of fuel in it when i got it so i used some diesel additive and filled the truck up. I have drove it about 200 miles and it is not getting any better. If anyone could help me it would be a great help!!!!

First thing i would try would be some Rev-x by far the cheapest and clears up alot of rough idle problems in these engine. I would stop back by the ford dealership and let them know you had a new FICM installed and its running rough they may be able to reflash it and that might clear it up.

I heard that Rev-X stuff is good. The truck spits and sputters BADDD from about 1200 RPM's too about 1800 RPM's and when going up an incline it gets worse. If I lay into the throttle it doesn't have the misfire feeling any longer just feels like it doesn't have enough power it get out of it's own way

Start with some rev x, being that it has sat for awhile maybe the injectors are funked up. Also check fuel pressure. I just recently had to replace my frame mounted pump. Started and idled fine, but step on it and no go.
