You should see some improvement with time. I was getting 10.5 average until i hit 1000 miles, now I'm up to 13.5 with 2000 miles, it got better fast. Thats mostly slow, city, hills driving. My MPG has gone down this last week with the install of a VR, mufflex, and heavy foot. Just received my BD and mounts but Im waiting for BD to run through some more patches before I install. We'll see what the tuner, some more miles, and a lighter foot will do. Im thinking the first oil change may loosen things up a bit too and improve MPG.
Please let me know how your trucks MPG reacts to the addition of the tuner. I will get one if its worth it. Thanks
