Mpg
When I first got the truck, I was only getting about 12-13 MPG.
With the Spuerchips tuner and premium gas, I averaged this last tank out to about 17.8-18.5 MPG. NOt bad. I have 12,000 moles on the truck now.
XLT Regular Cab, 5.4 3.55 LS.
I imagine by the time I finish modding it (intake, exhaust, tonnoeu) I will be reaching up into the 20's.

Well first off, using higher octane will geive you moe MPG anyway and the chip helped a bit too.
I think it was a mixture of both the SuperChips and truck breaking in. Also, I drive 65 on the Interstate instead of 75 now. I drive an hour and a half pretty frequently on the interstate. It doesnt get me there very much quicker to drive that fast and save me a heck of a lot of money round trip.
