I am very happy about this. 30-33mpg for my normal commute and 35-37 highway. 35mpg was sitting right at 80mph for the entire tank too.
Haven’t had a tank below 30 yet. But too be fair, I purposely didn’t check when I was in the mountains around tail of the dragon. Pretty wild that the Miata is a bit quicker than the Crossfire but gets significantly better mileage.
Progress, except for cylinder count but there is always time for that later.
