When mine had the stock tires, my computer was 2mpg off as well. (when it read 21.5mpg, I calculated 19.5mpg)
With the 33's and the computer not yet recalib. for them, it's reading 18.8mpg and I calc. at last fillup 17.6mpg.
Not reallly any rhyme or reason to those numbers, so I'll be interested to see what happens when I take her in on the 10th.
BTW, 6spd, mix of hiway and intown, no hotrodding, even clutching/shifting, no evasive manuevers or transmission braking.
2007 JK X 2dr. 6spd.
