My namesake was good for 8mpg, no matter what.

My brand new (at the time) 1990 D150 V6 5 speed got an honest 24mpg day in day out of commuting.

My 97 Dakota V6 auto 2x4 gets just over 18 in commuting.

Tuners are not magic, and if what the OP is saying is true, don't you think it would have become pretty much mainstream knowledge over the last 20 years?



I didn't say anything magic about the tuner and mileage! However the difference in power is MAGIC!!! I will be doing a video soon, my arm is still not back to full strength so it's hard to do things with it. But when I can I'm going to be some power videos and I'll put them on youtube and post a link on here. I'm going to do something with the stock setting and something with the 87, 91 settings. I can tell you I'm currently doing a city mileage test and it don't look good so far. And I'd have no explanation why there would be such difference in the city and highway mileage. I'll post #'s in a day or two.
