So I am aware that on a stock tune the STi (its an 06) runs pretty rich, but my STi is only getting about 16 mpg city. Is that normal? I bought it used and apparently it has a Perrin 3" DP. The rest of the exhaust is stock. Do you other STi guys get pretty shitty milage? Im in it hard sometimes, but mostly just easy to and from work rides. Dont have the money for Access port at this point in time, so thats not really an option to change the map. Thanks for any help.
