I would like to know if anyone has the Banks Powerpack with air intake, Headers, dual tip exhaust and their reprogrammer what kind of increase in miles per gallon have you achieved I have ordered this kit in the beginning of January I have 2008 F150 5.4 the best milage I have achieved is 23.5 with 800lbs. of hardwood flooring in the back and my friend was driving at 120 kilometers an hour for awile. I believe if I was empty and we kept my truck at 100 I may have reached 25 MPG.I also have treated my truck with
Bi-Tron products, which have helped both in power and fuel milage http://bitronglobal.biz/savebucks

 

Well, I guess it all depends what you are doing with your truck. I am not drag racing it and if I did do anything else, I would get the Torque Tubes.

I have two Fox Body Mustangs to feed my need to go faster. I was just looking to wake the truck up a bit, which this system did big time.
