BBB Big Bore Boss 322
I'm not intimidated by the wannabe "Wild West" attitude on this forum. It's like YellowBullet-lite over here. Whatever. I averaged 21.3MPGs from Fort Myers to West Palm to load the tune. Then I averaged 23.6 on the way home. That was about 80% Highway, 20% City. YMMV. It's hardly a scientific test, but the numbers are straight off of my personal vehicle. In the week or so that I've had the tune, the MPGs have never dipped as low as they were on the stock tune.
Were the same tire revs used in both tunes? The mpg will be off if that's the case.
