:?

I am not too sure. I am losing mileage with the same driving habits as compaired to my stock paper filter.

Here is the weird thing.

When I drive harder, my mileage goes up.

I installed the filter when I was at half-a-tank...I usually wait to do a mod on a fresh tank, but I wanted to throw it in there. I am using the AVG mileage reading from the first half of the tank on the stock filter, and from now on with the K&N. Don't know if that matters or not.

I love the small [if noticable] difference in power, but watching my mileage drop slowly while driving on CRUISE is causing me to become confused. Who said 45mpg? I called BS on that then and I still will.

Anyway, I'll be needing gas come the beginning of the week and we'll see what happens. I plan on running the 93 tune again at the next fill-up, and then switching back to 87.

Maybe I need to smoke the computer and reset the battery after installing the filter -- I always did on my other vehicles when I did the K&N FIPK. Hmm...

Anyway, when I drive harder, I gain mileage. Odd.

hard to say, I have never had that problem on any other car and I don't have one yet for my Fusion,
seems rather odd to me as well. yeah, I really don't see this car getting 45MPG even me with the 2.3
the new Toyota Yaris, boasts 40mpg but hello it has a 1.5L 106Hp engine, and even my '84 Chevette
got almost 35Mpg, when I wasn't driving the hell out of it, but too it had a 1.6 in it, smaller engines,
better mileage, but you sacrifice much power for the mileage abilities.

I was the one to claim 45MPG..... and here is the proof:
I drove to san diego about 2 weeks ago at a steady speed of 75 on cruis control.... my MPG kept steady between 40-44mpg....believe it or not.

Now that I'm back in town, and do 90% city driving... my computer shows 34mpg.... which is a whole lot better than what I used to get 19.6mpg..... and btw, my driving did not change.

I have no clue that is going on with your fusion Swoop, my best guess is that it might have something to do with your computer tuner that you got.... but then again, its just a guess... because like you said it yourself... the harder you drive the better gas milage results you get... which obviously doesn't make ANY sence....

How abnout this, set your tuner to Fusion stock setting, and don't use the tuner at all.... and see what happens... pahaps the onboard computer got overloaded or something.... I just Dont Know.

Good luck.

Dude that's wild. I don't understand YOUR car, and you don't understand MINE. lol.

Damn, I think that I am going to reset everything after this tank is burned through. Maybe I'll smoke the computer tomorrow and leave the tune.. Hmm. I have the next 4 days off, so I'm sure to get into something!

I mostly drive streets and before the k&n i was getting about 260 miles on 16 gallons, 300 miles when I traveled more on the freeway. I Installed K&N filter and removed the silencer box a few weeks ago. I'm now getting 270 on the street. I just took a trip yesterday to Tijuana Mexico, cruise control between 85-90mph both ways, I have 301 miles on the trip odometer and a 1/4 tank left. "68 miles to E". Only other factor to affect this increase is I switched my 19's for my stock 17's for the trip. If your wondering, yes I got a speeding ticket, 84 in a 65 NOT EVEN 5 Miles across the US border!

Few questions....

-Engine/Trans Combo
-Octane Used
-Method of determining MPG - Trip Computer or Miles Traveled / Gallons Used = MPG
-Type of Driving - Highway, City, Combo, Hills, Flat, and Approx Temp
