not good MPG

hey everyone,
i dont know if this is normal but i think my mpg is kinda low and is wondering if anyone has any suggestion. I am currently getting like 10 MPG and thats like really low i think.
I am running the utec with sti injectors , the last i dyno my car the guy told me i was dumping too much fuel but i am waiting to rebuild my motor first to tune my utec.
my car is an 04 wrx. just wanna know wht u guys think abt the numbers and if i have a tuning problem bye the way the car runs great as is now.

thanks.

u guys must be pedal to the floor all the time or u have a bad tune, try this boost 556, next time u fill up clear your trip odometer, next time u get gas divide total miles by how many gallons u put in the tank. check your tire pressure, try to get to stock specs if it's not

rollin on 17's now and they're dirty

That is absolutely horrible.

Tune your car man, you are running super rich.

Also sti pinks wont flow enough for a gt35r

performance comes at a price but not that much of a price. Its a 2.0l not a big block

02 rex is gone.
I defected to an evo :)
Evo is gone :(
Now I got nothing.

yeah.........I think i am running really rich but waiting to do my internals anytime now then will get a good tune.I think cause i am boosting high too and i do hit the gas pretty often lol.
I cleared my odometer and recheck it work out like 15MPG.but hoping to improve on that after the tune.

thanks.
