After 18000 miles on my 2015 Powerstroke, I am having found memories of my tuned F150 EB, so I ordered an SCT X4 from 5-Star. The tuner arrived Thursday evening and on Friday I loaded the canned tow tune. After about 300 miles, I will say I feel a small power increase and it looks like my fuel mileage may have improved. I may try the canned performance tune for comparison. The X4 does allow for transmission tuning, but I left that stock as I have no idea what to change for improvement.
I have submitted the 5-Star calibration sheet and expect to have my custom tunes in a few days. I am looking forward to that as the 5-Star tow tune should have a little more power than the canned SCT tow tune, plus transmission tuning that should make things even better.
While I got this truck to tow my 10K fifth wheel, towing season is over and I would like just a little more sport out of my truck.
I have no plans to delete and would like this thread to be for non-deleted tuning experiences.

I decided to load the SCT Street tune from the choices of Tow, Street, or Performance. While I was in, I checked the Transmission options and was surprised to find the same options for the transmission, so I check Street for that.
What a difference! I can feel quite a bit more power and the shifts are firmer. It does hold the lower gears a little longer, but will still engage 6th gear at 40 if not pushing it. This woke the truck up and made it more sporty. I am not sure how it will affect fuel mileage as I only have 15 miles on it. I will drive it to work tomorrow and that is a 74 mile round trip.
I now want to try the canned tow tune again with some Trans tuning to take the laziness out of the shifting and it should feel more sporty than the stock transmission did.
It was interesting, maybe because of the Trans tuning, that it took a while to load and seemed to load twice. The X4 is a lot more sophisticated than the SF3 I had previously (gone to the good home of a 4.6L owner).
The sweet thing about ordering from 5-Star is that I get three custom tunes for the same price I would pay for the X4 itself from somewhere else.

The 5 Star tunes showed up in my inbox late this morning. I spent lunch installing them on the x4, and loaded the Daily Tow tune just before going home. Wow! This is just what I was looking for! There is as much power as the canned street, but the transmission tuning was perfect. The shifting is quicker than stock and softer than SCT street. Where SCT held low gears longer, but was in 6th by 40. 5* only held lower gears slightly longer than stock, but doesn't hit 6th until 46 mph. One of the most annoying things about the stock tranny is holding 6th too long when starting a grade, bogging down, dropping to 5th and bogging again so a drop to 4th is needed. I frequently locked out 6th unless I was doing 50 or more. 5* eliminates the need for that. It quickly drops to 5th and keeps pulling with no bog. This tune has a perfect match with power and gears so they work well together. It appears to get better than stock mileage as well and better than SCT Street. Leaving a stop light is much more satisfying than stock as the lazy feel with light throttle is gone. The truck feels 1000 lbs lighter now.
The Daily Tow tune is a great job by 5-Star. Highly recommended!

That ought to pull a 10K fifth wheel like its not even there. My fiver has a typical road weight of just under 14,000 lb. and I'm very happy / impressed with how my stock '11 pulls it. I'm at about 25,000 towing miles (57,000 total) with no issues.

It was more about how it drove empty that led me to tuning it. I was pleased with the towing performance and have about 12000 miles of towing on the truck. Now it drives empty like I want it to, goes smoothly from a stop without the lag and doesn't shift to 6th to early.

I run the canned SCT tunes on my PSD too. I agree the real difference on the butt dyno is with the transmission tune in place. I run the canned tow engine + transmission tune currently and it works great!

I did try some PIP custom tunes and got to tell you was very disappointed. Waste of money. If you have the SCT tuner device my advice for all would be stick only with tuners that will supply a transmission tune along with the engine tune.

If you can get the shift into 6th delayed until 45 mph, the SCT canned tunes are probably fine, but 5-Star nails it with the smoother shifting, the timing of it and more power. I have a dealer visit in a week or two for 20,000 oil change and whatever else, so I will return to stock, then revisit the SCT tow tune with transmission tuning just because I can.
