I bought the 87, 89, 93 Performance/Tow tunes. I haven’t played with them all yet. Running the 89 right now and really like it. I had a tune from another company that wasn’t near as good as this tune. 5 Star knows their stuff! I have a 6” lift and 35’s which hurt the fuel mileage. I average 17-18 city/highway combined. I lost 3 mpg instantly when I installed the lift and tires when I bought the truck.[emoji85]
I use the sct bdx programmer but only to load custom tunes. That's all a programmer does. I would stay away from any "canned" tunes that come preloaded. I also have the 93 performance, performance/tow, and 87 performance/tow from 5 star. Here's the kicker though.....I upgraded the intercooler, charge pipes, cold air intake, turbos, flanges, and down pipes. There's not a faster F150 3.5 Ecoboost in town, maybe the state.
I would tell those who have custom tunes (or canned) to at least upgrade your intercooler for the longevity of the engine. The higher boost pressures from the tunes creates much higher temps into the intake which it's very hard on the engine.
Hard to pinpoint i think ive run 3 tanks through the truck and best average per tank per computer was 15.8 with 60% highway 40% in town. Experementing with 87oct, 90oct non ethanol and 93 oct
My last 2017 would get 21 or so on hwy and 17 in town. With smaller lighter tires.
This one im guessing is 17 on HWY and 14 in town. Much lower. Just hard to believe that much reduction with the tires
