Just got my 2019 F150 Special Edition about a two months ago and was happy with the truck but disappointed with the lack of performance and how sluggish the transmission acted. So picked up one of these tuners from Livernois about two weeks ago, Installed the 93 octane performance tune and their calibration for the 10 speed transmission. Since then I have experienced a huge increase in performance, while at the same time getting better fuel economy by .4 per gallon, and the transmission now shifts like it should using all 10 gears. My favorite thing has to be the way they calibrated the transmission, before it would skip over gears and always felt like it was slipping, now it grips and rips. I would NOT own this truck without getting this tuner, it should be an option that’s offered at the dealership. Livernois killed it with this tune and the trans calibration. Check out their YouTube channel

Did you try sport mode before buying the tuner? Just curious.
