Reason i ask is because i get about 205 miles to almost a full tank with the AC on and about 216 with it off and thats going pretty easy on the pedal...

Is this right????

205 sounds a little low, Mustangs have a 15.7 gallon tank.

You don't own a lightly mod'd Mustang GT and drive it like it's a Buick Century.

well before i started putting mods on her she was getting like 240-290 per tank (91 octane) depending on hwy vs. street and no a/c. your 205 sounds a little low to me. but the way i look at it, more air, means that your computer should put more fuel in I.E. worse mileage? not sure if thats right. i dunno that much about the ECC-IV's or what ever it is that we have. But it looks like all you have for more air is that FIPK.

as far as the fuel tank. when i drive around with the low fuel light on for like 15 miles i go for a fill up and the most i can put is high 13-14 gal. i dont have my owners manual any more (long story).


also since my mods, i get about 190-260 street- freeway with the a/c on a little bit, not all the time though.

I get 175 easy city driving IF I'M LUCKY. I got about 200 if I drove like a complete pansy when I drove it off the lot, til I did my exhaust. Be happy you're getting 205.

I wonder why it varies so much.

I can whip the **** out of mine and still get 20mpg easily. I get 26 on the highway and have had as good as 28. All on 87 octane.

Piss-poor factory "standardized" tuning.

I've tried shifting at 2k, 3k, 4k, etc.. always the same pretty much. <200

Lately I have been considering getting it checked on also....
I seem to have to fill up every 3-4 days with pretty minimal driving....Sure the a/c is on now, but it cant be the only reason...
what could cause such gas consumption. I know ls1/lt1s that fill up less often then me.

Yup. I'm with you guys. Once I hit just under 200, the "hey a$$hole" light dings on. But then when I go to fill up, I only fill 13 gallons. So it ususally equals 16mpg.

I'm thinking of getting a tune up in hopes to correct this. Maybe a faulty seal or something?

Well i just got off the phone with the local ford dealership and he is saying that i should have my fuel filter changed and it would fix the gas consumption issue....

The car only has 13K miles on it does that sound right???...

Idk, mine is an 00 with 23k miles on it. Excuse my ignorance, but is the intake filter the same as the fuel filter?

Oh no, they're two different things. And they're pretty self-explanatory.

Fuel filters aren't supposed to get dirty until 20-25k, unless it's seen crappy gas all its life..

I get better mileage than that and I got 4.10's. heck I got better than that with a night at the track too. Also so far I've knocked down my best MPG shifting at 2500rpm. Now GIt-it you gotta tell us how you knock down that kinda MPG.

My god, so where can I pick up a new fuel filter and I'm assuming it's just a simple drop in, right?

Ok i just checked my owners manual and scheduled maintance manual and at both the 10k and 15k service it does NOT state to have my fuel filter replaced...
I guess the guy up at the dealership was blowing smoke up my a$$.
