Angry high egt making me crazy

hello to the forum members been reading this forum off and on and now need some ideas with my problem.
i have a 05 f250 6.0 having high egt problems, i noticed them creeping up over time. cruising at 50mph flat ground is 850*-950 70-75mph is 1000*-1100 flat ground climb a hill they go up from there. So in the last month i have replaced oil cooler,egr cooler delete,egr delete, new glow plugs and harness, hpop valve,
dummy plugs, ats aurora 3000 turbo and ford reman injectors, new egt probe and a few other misc stuff that i cant think of at the moment. and still geting hot. Im running a sct tunner with looney tune. i have tried stock tune and everything else and not much difference. The egt probe i know is located wrong by previous owner its in the drivers side rear exhuast port instead of a couple inches back but the temps were never this high till recently, before i went on the spending spree. i checked the manifold temps with my temp gun and the rear cylinder is running hotter than the rest and equall to the egt guage within 30* or so, and left side is 100* hotter than right. the #8 injector was overfuelling and 3 on the right were miss firing. thats why replaced the injectors, its acting like the same things happening with #8 geting hot and over fueling. i would appreciate any ideas

Looks like you tired just about everything. But just a thought... Since your running a non vgt turbo, doesn't a custom tune always need to be used? Probably isn't a factor but what about the FICM volts? Is it tuned? (The FICM). Any chance the egt probe tip is touching the exhaust manifold?

thanks for the reply. the guys at ats said that the 3000 turbo set up would work for stock settings and should actually be running a lil cooler. my looney tunes is supposed to be for my turbo setup. i havent tuned the ficm yet one of the few things i havent done but want to try and voltage checked out good. i tried spacing the egt probe out more but no change. thanks for the ideas and welcoming me on the forum. Have u tried the ficm tune. any positive change for $300 spent.

I haven't... There is lots of threads on FICM tunes though. I'll tell you one thing and that seems to be common though, all FICM tunes increase EGTs. I thought maybe your were running a hot FICM tune.

nope just a hot truck lol. and weird its just the one cylinder running the hottest. unless theres a short in my harness casuing it to over fuel but the harness looked good no cuts or frays in the plastic loom to make me strip the loom and look further. thanks for the heads up on the ficm tunes might steer clear of. them with my current problem.

Im not pleased with my egt's as well. Curious if you have thought about having your intercooler cleaned or maybe going with a aftermarket set up? Im also lookin at water methanol set up but gotta get that money sucking thing called christmas over with first!

havent thought much of cleaning the cooler but might be worth a try doubt its plugged,theres a shop a hour or so away that we send all our heavy equipment coolers off for rebuild im sure they would do it gotta look at the cost of cleaning to new ratio. ive looked at the aftermarket coolers from what ive seen from other forum users theyve seen maybe 100* difference wich is a improvement but is that worth the $$$
if im wrong on the temp difference from anybody that put coolers on let me know and what brand did you use.

That brings up a good point… your a/c condenser, radiator or infer cooler could be plugged with dirt and bugs. Might try your best to clean themc it works best to use compressed air and blow the crud back outwardly the grille, instead of trying to push the dirt/bugs further into the coolers (towards the truck). How is your fan clutch… try the boom stick test
