TOPIC: 2003 F-150 5.4 V8 does this vehicle groove well???

Looking at buying a 2003 F-150 with a 5.4 V8 but the gas mileage is 12. Anyone done one and what kind of results could someone expect??? Thanks, Allan

yes many, if its a 4x4 16 to 18mpg 2 wheel drive 18 to 21

Hi Allan, Yes, I just did one, too soon for MPG data, but the truck responded beautifully, substantial power & throttle response increase, and clean smelling hot air at tailpipe!
