That is a beautiful thing! Performance Tune here I come!This statement on the product description on the ford performance website is definitely new
My experience is almost the opposite. I think it has more grunt in the low to mid range and seems to skip gears a lot less. It seems more responsive in traffic and seems to downshift quicker. Initially I thought it shifted up too soon but as the transmission has learned it feels better than before. I guess more people will weigh in. The more I drive it the more I like it.I know nobody asked but I'm going to give an initial review of my experience with the new FPP tune update in comparison to the first FPP tune. After ~50 miles of my typical route:
Truck feels less snappy off the line, and about the same when doing a rolling WOT punch.
Initial transmission feel was lots of bucking and hard shifts, but has smoothed out considerably and does not seem to hold gears nearly as long.
MPG seems to be slightly down, but could be due to the tranny re-learn or many other factors (fuel, air temp, barometric pressure, etc)
I suspect that the change was mostly lowering boost pressure, and restricting the tranny shift points to a certain rpm. AFRs probably aren't as lean also which would explain the loss of snap off the line and the MPG decrease. Doing all of these things means safer temperatures during towing operations.
I do tow often enough that I might just keep this tune on, but it is so easy to flash over I wonder if Ford Performance would let me have my old tune back if I desired? I might send an email to see. It would be nice to have both IMO.
Thanks to you both for sharing your experiences with the updated tune. As I rarely tow, I'll wait a bit to see what the general consensus is on the update before installing. Almost rushed right into it, thanks again!My experience is almost the opposite. I think it has more grunt in the low to mid range and seems to skip gears a lot less.

I know, I found that peculiar. I was expecting the changes that you had mentioned but kept experiencing the opposite. My low end seems to be less than before (I could chirp at any stop if not careful) and now seems to take a bit of an effort to chirp. I also travel a grade that would hold the tranny at some gear (XL trim, no read out, so I'd be guessing) @ around 4k RPM at 69 MPH unloaded, and now it upshifts long before that. This is all in D, I haven't done the route back and forth in S yet.My experience is almost the opposite.
You can plug your ProCal 4 tool into your PC with the Procal software loaded and it should detect an updated tune and download it to your tool. I have also linked the ProCal 4 instructions:How does one check for and download the update?

Would be interesting to see a badk to back dyno run of old and new.I know, I found that peculiar. I was expecting the changes that you had mentioned but kept experiencing the opposite.

I will drive it at least 2k to decide if I like it more or less.
In D, if you hit the "shift up" button it will toggle the gear display in the center screen.I know, I found that peculiar.
