Bad Gas Mileage!! HELP

[ib_604]

of course you don't buy this car for getting great mileage...but obviously if for no reason for MPG drops big time, there might be a problem....

i have had the car for 2 years and was getting a lot better mileage then i have been in the last month.

You guys do realise that this car in full boost will drink a gallon of gas in a 1/4 mile right?

:lol: Getting into boost does command more fuel, but not a gallon a 1/4 mile pass!

Update:

I finally cleaned the MAF with some SensorCleen, drove the car on the weekend, but still getting crappy mileage...

looks like i will be dropping the car to my SVT dealer, and getting him to check it out, and probably getting a re-tune...

UPDATE:

my tuner called me today, he did a re-tune, and said the car was running rich, so he fixed that...

also, something about my 3.73 gears not being installed properly, and that could be causing some other problems...

bottom line....new tune installed, putting down a little over 460HP @ the wheels, plus i am gonna go with some FRPP 4.10 gears, and an oil change...gonna be a big bill...kinda expected it though.

Improper gear install makes for bad gas mileage??hmm

 

[ib_604]

i think it just makes the driveline work harder? not sure...

I got 14.7 mpg this week with 3.73's and 2 3rd gear pulls, otherwise shifting around 2000.

who is your tuner??

bad gas mileage so now your gonna install 4.10's, hmmmmmmmmmmmm

 

[ib_604]

lol, after much consideration, and reading reviews on SVTP i decided to stay with 3.73's...

never really race the car, its more for cruising and that, plus i may consider a steigy port in the future, rendering 4.10's useless....

Did you put the fuel filter in backwards?

I'm getting bad gas mileage. I had a ford dealer change my fuel filter. Should the flow arrow on the new fuel filter be pointing towards the driver side??

If my memory serves me correctly. No.

I just looked this up. The directions here says that the flow arrow should point to the driver side. Hard to believe

I thought because the fuel lines were on the passenger side of the car the arrow for flow would point that way.

I thought the same thing. The fuel lines must curve around. I asked about it in that thread but No body will reply back to me but whatever.
