Default Diablosport Predator 2 Platinum with 2018 F150

Hello all
Just thought I'd post this so noobs like myself doing research on tuners have something to see.
2018 F150 2.7L EcoBoost crewcab XL STX 4x4.
20x9 +18 offset MB wheels with Nitto Ridge Grapplers 295/55/20.
Motofab 2 inch leveling kit, stock rear block
S&B enclosed CAI oiled filter
MBRP XP series cat back exhaust 4 inch
Diablosport predator 2 Platinum tuner: 87 octane economy tune.

Done a couple of weekends ago without Diablosport economy tune. Cruise control used for the entire run. Eco mode on.

Done this afternoon after Diablosport economy tune, same road (backroad highway with slight hills) same speed at about the same miles, Normal driving mode (eco mode off for the entire run). Cruise control used for the entire run.
Gain of 3.3 mpg.

Second run with Eco mode on the entire run.
I had to cut the second run short because 2 loaded semis pulled up in front of me. Will try the run again in the morning.
With the economy tune on normal drive mode, the truck is a beast! I was shocked that even in economy tune I was chirping tires shifting to third. Gears seem to want to hold at a higher rev rate, and don't want to drop to a lower gear so soon as it did in stock.
I do have a concern though. To get to this road, I traveled on a freeway for 24 miles and doing the speed limit of 80 mph. Although I did notice a slight mpg improvement (from 13.1 mpg to 13.9 mpg, very hilly freeway) I also noticed that the truck wanted to stay in 8th gear most of the time in those hilly areas (as opposed to stock tune which would downshift to 9 in stock tune). She did not want to get out of 8th until the road was completely flat. I don't know if that's part of the design of this tune, and it very well could be, but it concerns me nonetheless.
Anyways, this isnt scientific or anything, I just thought it might be good for someone who's thinking about it for their 2018 F150. So far, I'm impressed. But I will continue to test this tune and the rest of the Diablosport performance tunes in the real world.
I hope this helps someone.

Uodate: 09/30/2018: I do this 80 plus mile run every weekend to shop with the wife. This is a rolling start at 65mpg for 13 miles, transitioning to 75mph for 30 miles then 80mph for the rest of the highway trip. In pure stock truck form, i averaged 17.3mpg. With current truck setup without tune it dropped drastically from 14.9 to 15.4mpg. This run was also done with the front air dam off, which i heard steals a mile or 2 of mpg at freeway speeds. Dont know if thats true.
I'm completely impressed with this Diablosport predator 2 platinum tuner.

4 out of 5 stars for the S&B enclosed CAI. Sounds great. Looks great. Super easy install. Improved throttle response and power slightly. However, do not expect improved fuel economy. In fact, I lost about 1mpg at least. But it's fun stomping on the gas with this and the exhaust and tuner installed.
