I use a gps for mileage and speed as my speedo is off by 2 mph. No tuner just volant intake and megaflow muff. I get 14.5-15 around town when I have to. 16.5 all around type drive hwy & town. Back and forth to work 70 miles round trip 18mpg. So not to bad would like a little more, hoping a tuner might help. Ditto on the overhead I think cause the speedo is off? 3.78 I believe in the rear end, Sometimes coming down the grapevine with eb on i can get 99.9 mpg if I reset the overhead at the right time. LOL And on pulling I have about 13000 on 5er I get 10-11mpg depending on which way the wind is blowing
