I've been driving 8 cyl pickups for a lot of years so maybe I'm just expecting too much from this little 4. I bought it to save some on gas and will do light hauling once in a while. Have a 2008 l4 access cab 4x4 w/cap. I'm seeing 17-19 mpg (city) so far after 1500 miles. I assume that because it's a 4x4 I'll never see much better. My biggest concern is that mileage will go to hell when I have a moderate load on the highway, as it seems pretty gutless just driving around town. Your thoughts???
Also, what mods will enhance the performance...best bang for the buck? For power and/or mpg.
