What is your Civic SI's best MPG?

im a average between 31 highway and 28-29.7 city all depends I mostly drive highway during the week
 
The car tells me I am averaging 27-28mpg and the highest was 34mpg(highway trip), but when I run the numbers on the Fuelly app it is all 2 mpg lower than what the car tells me.
 
I average 22-23 mpg tops about 27 but i drive 40%:vtec:and 60%:driving:Should try a full tank on easy mode but that's so hard to do.
