Running a stock 2005 4X4 Quad Cab 1500 with auto trany. Looking at installing a cold air intake and maybe using the preditor programer. Have already installed the ground effects package along with a tonneau cover and rear spoiler, now getting ready for engine mods. Any ideas why the gas milage is so low on the highway ....10mpg
