I should have mentioned earlier - one of my original goals I still have is my "55/55" goal - - - to get 55 miles per gallon while going 55 miles per hour. As far as I can tell, I still can't do that, but it's a little difficult to test, long-term. I can be going down the road at 55, reset the ScanGauge for "trip-current", and watch the average develop, but that usually ends up being around 51 or 52 mpg.

Of course, unless I filled up alongside a highway somewhere, immediately accelerated to 55, and then held it there for hundreds of miles until pulling off at another gas station alongside the highway to re-fill, I won't ever be able to say, "this tank was at 55 mph". But once I get the boattail/kamm back installed, I may try a somewhat extended run (a few dozen miles, maybe) using the ScanGauge "trip-current" feature to test it.

Otherwise, I'd be thrilled to see a 70 mpg tank average someday, but again, I expect it would take some "maximum effort" dedicated trip for that, too. That is, fill up, drive continuously somewhere with almost no stops, do "potential parking" at the midpoint for lunch (or to spend the night), then take off & head straight back, minimum stops, so the engine and system is at full operating temperature 99.9% of the tank, and no energy is being wasted braking, backing up, and accelerating.

For more "real world" goals, I notice it's been almost a year now since I've got LESS than 50 mpg. Maybe - just maybe - I can get my "official" 90 day average on this website to 60+. I would be very happy to accomplish that in the next few months. - and I've got my first 60+ tank of the year to start working with!!!
