I can tell you all of these changes really add up. I did some 50mph cruise testing by running north, then south repeatedly on the same road with cruise set at 50mph. I eliminated the variable of acceleration and reset my mpg on my scanguage as soon as I hit 50mph on each return trip. This was done on a 2.4 mile road with 12 total trips (6 round trips) and saw an average cruising mpg of 52.25mpg. This was done at a frigid 21 degrees-f. Before all mods, the best I would have seen would have been around 44 to maybe 45 at best. Last winter I saw a couple trips that were 47 in similar areas, but those were rare. I struggled to top 44mpg without mods.
I love this hobby!
