Greetings! I recently had installation issues with iTSX on my 2010 F150 XLT 4x4 which were FINALLY resolved in the latest update. I don't believe this would have happened without those un-identified applying some well-deserved pressure to SCT! To those unknown I am grateful! Now, I have run the trailer program with 10% shift improvement today in the Florida kKys without my trailer and I was extremely pleased with the mileage of 10 L / 100 km...or 24 US mpg and 28 Imperial mpg if my math is right...at about 70-90 kmh. These are numbers I have never seen with my truck. I do have a Magnaflow cat back exhaust which has also noticeably contributed to this improvement.

Let me know (share) your experience with different setting so we can all benefit from your experimentation!

Wow, that is impressive. Definitely looking more at these now

Yeah..keep in mind I was light on the pedal for sure but going with all the traffic flow.

Hell, I was light on the pedal yesterday on my 340 mile trip and my trip computer read 16.4mpg, so I probably got more like 15mpg. Best I've gotten out of it, ever, was 17.5mpg. I know it's a truck, but a few more MPG's would be awesome. Not to mention a firmer shift and no lag on the downshift when I floor it to pass someone (who's awesome idea was that, anyways?)...

Haha! LMAO (laugh my *** off). Today was a different story kicking it up a bit on the speed in central FL....running 120 km/h plus while pulling trailer and only got about 20 L per 100 km. I guess speed and trailer are not a good combination for any day! And no, I am not surprised.

Towing an empty 6x12 U-Haul trailer the other week, I got 11mpg on mostly highway driving at about 70mph. Driving the truck from North Carolina to Missouri with a 2500lb 5x8 U-Haul trailer, the wife got 13mpg.

How does it shift with the tuner on it?

MuskokaRocks

I am right in there too at the 12 us mpg with 2500 lbs load. The shifting seems to be fine although I would like to experiment with it a bit more. It seems to roll off the line slow and smooth them kick in the pants with a jump and move up through the gears from there ok

Well I'm running the 10% increase in shift pressure, with 87 performance tune, I think the truck shifts too early and seems to lag in 2nd gear. Also doesn't down shift has quickly as I would like, I guess to many years of driving a stick...

Sweger

How's the fuel economy with the tune you're running?

I'm averaging about 15mpg when I'm not playing around, I had it up to 20mpg on a 200 mile trip. I was average about 17 around town and 22 highway before the iTSX but I also went up to a 285 70 17 tire at the same time. I will air the tires up (lower pressure for better ice traction) tonight and remove the ballast weight from winter and see how it goes for the next week.
