2011+ 55-60mph 5.0 Shuddering and EcoBoost Engine Miss/Loss of Power - Possible Fixes
Tech said he tried all the suggestions from Ford engineering, and it is now back in their hands. They haven't given the dealership the new software yet. Bob_Mac, did they have to request this special for you, or already had it handy?
EDIT - Also the issue seems to be related to one bank of cylinders. Not sure if this was the same cause you had BobMac

This is NOT a tire issue. This is a definitive hestiation/miss/shudder at 55-60 MPH in 6th gear at 1500-1600 RPM. I have the 18" chrome wheels with the Goodyear tires and recently put on the 18" OEM aluminum wheels with Blizzaks. I had the hesitation/miss/shudder with the Goodyears and same with the Blizzaks. I stood in the garage with a friend of mine who balanced the tires so I know they were balanced correctly. I have printed out some of the information that Bob_Mac has posted and will be taking it to my dealer next week for my appointment.

Got the truck back today. They did find a misfire on #6 using the mode 6 procedure and went through the same clearing procedure that Bob_Mac posted in the first post. First thoughts are it seems to run better for sure. My second issue was for a shudder the truck does when I come to a complete stop. The dealer did said there was a program update for the tranny so they loaded that up. The shudder is still not completely gone but seems to be going in the right direction.
I don't have paperwork at this time to report any numbers of procedures as the dealer is leaving my work-order open as they want me to a couple hundred miles on it so I can report back to them if things are better for one or both issues.

Your shudder is different than the 55-60mph in 6th gear up an incline so your shudder may be an entirely different fix. At least your truck is running better after the misfire clearing...
I have yet to see the shudder come back so my hope is that this was indeed the fix, one thing to note though is I had the high solenoids replaced and an update on my tranny which did help a lot with the shudder. Waiting on others to report on their dealers findings/resolutions.
