It can take a while for the PCM to learn your driving style, sometimes a 100 miles or more ...

Aside from that, tires and old transmission fluid are at the top of the list.  Then the PTU.

I would give it a couple of days of normal driving, check all fluids, then give er heck

I gotta say your post was reassuring. I might add, they are pretty new tires, did a full tranny flush before install of the tune. Is it doing damage when it gets in between gears like that? Its still under warranty and I work for a Ford dealership so worst comes to worse, something would need replaced. Have you heard of anyones getting in between gears like that?

If the issue is mechanical, yes it could be damaging.  The odds are against mechanical damage at this mileage tho.

You might want to pull and verify (or change) spark plugs.  Clean both MAP sensors with MAF cleaner.

I bought the whole kit from LMS plugs, CAI, 3 bar map, tstat, and tuner. Did fresh oil change and flush. I did check for any DTC's after and I didnt have any. Didnt smell anything weird either. I'll drive it for awhile and see if the problem eventually remedies.

I recall when I first installed my freshly new tune for the first time that the first handful of WOT 1-2 shifts were VERY Harsh! They eased up gradually in time and is fine as can be but that was in Desired Drive mode! Not Sport mode FWIW!  Z

Did it ever seem to miss a shift? Weirdd stuff.

IMHO Don't recall! this was roughly four years ago!
Note - The vehicle should be running @ its optimum level before installing a new Tune with fresh fluids and all as mentioned by others. 

I wouldn't hesitate to email them @ tuning@livernoismotorsports.com or info@livernoismotorsports.com for any such inquiries. Z

Agreed. I did a full oil change, and transflush the day before tune.

mine a few years back, manu probably remembers had a shift problem of down shifting were would go into limp mode for a few seconds. dealers 2nd attempt was to run a tsb, 1st basically ignored me. thank goodness for the tsb update as made the problem so i could make it happen. turned out after much going back & forth between ford & dealer was they replaced the 2 sensors in the tranny. has been fine since. but was scared to take it to the max lms tune for older 10-12's of 4x as shifting was known to be stiffer so just took her to the 4+ & no issues
