What tune would I do to increase fuel economy. I love my truck. It drives great but it eats fuel up like no tomorrow. 295 miles on a full tank (24 gallons) that's pretty shitty and everyone tells me I should be getting better because I have the 4.7L motor in my truck
That's terrible gas mileage. I'd suggest you figure out why it is so low before buying a tuner, you need to get the engine to good order first. A tuner may give you 1 or 2 mpg but I get about 16 city and 21 hwy with my 4.7L.
Are the spark plugs oem? Any check engine light codes? Is it lifted, oversized tires? What modifications are done to the intake? Any other modifications?
Just curious but I'm assuming the lower horsepower 4.7 is the one have that is a flex fuel.Mine is an 07 and ive been wanting to do some power upgrades pretty badly considering i lost alot of power distribution when i put on my 35x12.50 MT'S
