My head is spinning!!
I have an 05 F150 5.4
Put new/bigger tires and wheels on, and want a tuner to help me keep things calibrated. I also want good fuel economy and performance. The truck is stock with 3.73 gears. I might want to put a CAI in the future, and udgrade the exhaust in the future (when needed). For now, I do mostly city driving, never WOT. I want to maximize fuel economy but not have a dog.
The other issue is that ALL the gas here has 10% blend of Ethanol, so any tuning I get should account for my gas blend here in MN.
I purchased the truck used, and have no idea if it was programmed before - Does that matter? The speedometer was always off by 3-4 MPH with the stock tires/wheels. The truck is totally stock (I think) with the exception of the FX4 wheels and tires I just put on.
Thanks for any suggestions!
Troy
