Stock I got 24 city, 30 hwy.

Heavily Modded I get 24 city and 21 hwy.

 

last tank of city driving was 23mpg and mind you I'm a spirited driver.
Last tank of highway mileage was 28 and again thats with lots of downshifting and such.

Just have the FiPK and invidia catback mileage was just a hair better after mods.

 

26-29 with a mix of city and highway and some vtec for good measure

 

getting about 22mpg.

 

18~19MPG city
21~23MPG hwy

AP1 with CAI and 4.77 gear

Something wrong with my S, or my driving?

 

Around 21 to 23 mpg in LaLaLand moderate city driving.

 

Around 23 mpg with AEM CAI if that makes any difference.

 

Maybe that has something to do with it?

 

27-29 highway
22-25 city

 

Me too

9mpg on the track.
