Gas mileage after mods...

[thump]

I've been reading alot on these forums now and Ive been thinking about doing all the big upgrades (bigger injectors, fuel pump, bigger turbo, FMIC, etc...). But one question has kinda been eating away at me, what kinda gas mileage do most of you guys get after you do all of these mods?

I quit looking at gas mileage once I started adding mods. My mileage is not TOO bad now, but I have seen a negative impact.

I have also seen about 10-40 miles less to a tank depending about how much I'm on boost.

Im running 750 inj, large turbo, cams, large FMIC, etc... and i was getting 25mpg on the way to the Shootout last weekend. Pretty repsectable if you ask me.

so there isn't a real drastic change? Thats good to know.

i think your driving habits are going to be a large factor in how much gas your car consumes...

Driving habits are a huge difference. I get about 17mpg, but I'm in traffic or flying at 90+ 99% of the time. My fuel system is almost stock (just an AFPR). So it has to be my driving.

No change at all. I've consistantly have been getting around 350 miles per tank when I was stock and even now.

I was a little over 300/tank when I first got my eclipse. Now I get about 220-250 (if I push it). I found the "error" of our gas gauge to be a benefit actually. I know I can drive round trip from home to work with the needle on "e". But then I better fill up when I get back home. Decided not to fix it after I found that out.
