Engine tuner for mileage?
I just bought a 2013 F150 XLT Crew with the 5.0. and 3.55 axles (50Kmiles). Really like everything about it. I am getting around 19 combined MPG and can get just over 20 @ 70MPH.
Will a tuner like 5 Star with an economy tune gain me much in the mileage department?. What can I expect? How easy is it to switch between tunes or back to the factory settings if I want?
What about engine longevity? Is an economy tune hard on the engine?
good luck -jim
Last vehicle was on '04 Crew with the 4.6 and I got by just fine with that power. It has 333K on it right now and I want my new truck to get there as well.
