So i got my car tuned yea..last week....so i tested my gas milege, and i figure maybe it will be a couple higher (out of the year i've had my car it's never been over 25mpg) and so i tested it and it was
33mpg





it was all highway but still...???? i'm gonna test is again tomorrow after i drive 50 miles to my bf's house...
