Evo 8 bad MPG!!!

hey guys I drive a 2005 Evo 8 with the following mods megan manifold, hks carbon ti exhaust, injen piping all around and injen intake. I'm getting 250 on a full tank without boosting at all is that normal. btw the car is on stock maps. I haven't tuned it yet. Do you think that is the reason why I'm getting horrible mpg if i boost i get 200mpg for a car that is merely stock.

I would say that is normal for being on stock maps. Stock runs very rich so after you get tuned you should see a little bump in mileage. I see your in Houston, is it cold there now because cold weather also decreases mpg. Im in NY and its below freezing and my mpg sucks balz

Yup, pretty normal. I get about 240-260 CITY, 260-280 HWY. My car is all stock with just a tune from GST. 220 ish a tank if I do some spirited driving.

Sounds about right for mixed city/highway. It seems like the gas light comes on so early in my car. Every time I fill up the pump stops at around 10.5 gallons. I believe the tank is around 13.5-14 gallons. I usually get about 250 miles before I fill up my tank with 10 gallons. 250miles/10.5gallons=~24mpg mixed with some hard driving, I have similar mods+tune.

Anyone else's gas light come on super early like mine?

Sounds normal.....
I have almost all the bolt ons on my IX with the stock turbo and the best I can get is 200 miles per tank, I usually get less than that though.

I get around 250 kilometers on a full tank.

Am running 720 injectors and FP Green might just be a victim of a bad tune.
