You should flash it back to the stock tune when brining it back in case the hook it up and check for Ford updates. Some say otherwise but that's what Anthony from Livernois suggested.
Even if you take it back to stock they still have a way to find out that you flashed it. Also unless there is a recall saying that the PCM needs to be updated there is nothing that can be done to say we need to update the PCM with a scan tool. The reason I say this is because Ford will not pay warranty if there is no bulletin saying to reprogram the PCM. Also the dealership would have to request approval from the customer in order to flash the PCM if it was customer pay.
That's what I said? For the 2-3 minutes it takes to flash it back to stock why not do it? I know you say it takes 2000 + miles to "re-learn" but I've never encountered that. Maybe a couple tanks at most but I have no scientific proof just seat of the pants feel.
I have never experienced the learn mode rough transmission shifting. Ever. Shifting didn't change after I bought the truck to when I installed the tow tune. I ran the tow tune for ~3000 miles and it never changed. Not saying it doesn't happen, just not with my truck.
With the 91-93 performance tune it shifted a little harsher at first and mostly gears 1-3. Not bad but noticeable enough from the stock tune. After about 1-2 tanks it was basically gone. I only ran the tow tune for one tank and didn't really notice it at all when running that one. I just prefer the 91-93 performance tune.
So I've been doing some testing with a couple of the Livernois tunes this week/weekend. I flashed to the hottest tune on Wednesday evening and didn't hit it real hard until Friday night down on the local strip. Then I drove 3 hours (200 miles) up into Wyoming this afternoon/evening (just got home) to take the granddaughter home. I kept the performance tune installed on the way up and flashed to the tow tune for the ride home.
I like your review. Something to keep in mind about the speed limiter..... Make sure you dont set it for above the speed rating on your tires!! Just a safety aspect there. Also if you are building your truck for Offroad(even if it is light) your tires probably wont have a very high speed rating. I think the factory tires are a T speed rated. That translate to 118 MPH. Most All Terrain tires will be an S Speed rating or 112 MPH so just be aware.So I've been doing some testing with a couple of the Livernois tunes this week/weekend.

So here is my two cents....and that's about all it's worth....lol. I see why Frenchy likes the tow tune. I believe I will keep the tow tune installed during the week for commuting on the interstate. Don't get me wrong....I absolutely LOVE the hot tune and will definitely flash to that on the weekends. It is very fun to drive with that tune running around town. VERY quick! So it is the tune for the low end to mid power band and the tow tune is definitely the tune for the mid to top end band. The only issue is top end. I could not get above 110 mph with the tow tune (will talk to Anthony about that). I have not tried the top end on the performance tune.
As far as the shift goes. I don't feel that the performance tune with performance shift, shifts that hard....lol. I like the way it shifts and I hope it stays that way.
The way my truck comes out of the hole when you romp it and through the first 3 gears is extraordinary! The way the rear end kind of bumps sharply to the side but stays nice in space is wild!
With the tow tune....it felt like it just wanted to eat up the pavement at 80-100 mph driving down the interstate! The tow tune seems to hit fairly well on the low end too.
So I love both of them for their respective differences with the very short time I have touched them.....always IMHO
Very good point on the tire rating Frenchy!!
I love my Livernois tuning also! I have noticed a couple of things but nothing bad. It feels like I get a little kick in the pants when she's downshifting sometimes. Also, my exhaust system must heat up a bit more. I'm hearing the metal make that ting sound here and there when I stop at lights and after driving when I pull in the garage.
Yeah that lovely jerkyness is the learning procedure. Give it quite a bit of time and that will go away for you.

So I’m staying with the hottest tune for my full time daily driver. I probably won’t switch tunes again unless I’m towing. Now as far as loading tunes, when I had a very long talk with Anthony from Livernois and expressing to him how I love that harder shift. He told me whenever I feel the shift soften up just reload the tune to get it back fresh into learning mode. Won’t hurt anything.
