yup got it from ford, they gave me a great deal on a new crate motor, it has less then 10,000 miles on it now. I live really close to Roush Yates engines, i almost just had them build me one but instead i opted to go back factory. You see, i'm not into it for the horsepower, i just want something that will get out of it's own way with some real tires but was decent on gas, i never plan to pull anything. An I also replaced the M5OD-R2 5spd trans with a fresh rebuild... when i was breaking in the motor & trans everything was stock, i was around 17ish mpg. i wasn't really paying attention, the first 3000 miles, then i did a test run to the beach and i realized early spring last year, i was way down on my MPG. So i threw the e3 plugs in and chipped it... I drove the truck on a 2000 mile round trip to go snowmobiling in February and i was hitting 22 mpg with ease.
Now if your that guy, who has to run 75-80 mph everywhere you go? good luck on getting any decent MPG... but I just putt around and just keep up with traffic, if i wanted a sports car, I'd drive one.
