Just curious what any of you guys are getting with your f150's. My father has a 05 f150 cc 5.4l 4x4 auto with 3.73's. It only gets an average of 10-12mpg city/highway driving. It might see 7-8 when pulling a 5k lbs. camper. Anybody else seeing mileage this bad in their f150? The truck is bone stock with stock tires. He has had it relflashed and nothing has changed. If anybody has any input to help improve MPG I would appreciate it. I know theres some programmers out there but just wondering if thier worth it. Thanks.
