Thanks,

Yeah I was wondering the same thing. Im assuming getting a custom tune would help considering the car runs crazy rich from the factory. hehe

 

I think cobb access port has an economy tune

 

The GST map and pill will get you 2-3mpg if your careful. Adding a larger FMIC should help too.

 

any custom tune will save you a nice amount of fuel.

 

Installing a less restrictive exhaust will always increase fuel economy.

 

Driver mod will help too. Stay out of boost lol.

 

im thinking best bet is AP for econo map and performance map when u wanna do some spirited driving. i didnt notice any gains in mpg with my current mods, if anything i lost 2-3highway

 

When I changed my original summer tires + rims for winter tires + rims (16" OZ F1 rims + 205/60 Nokian R winter tires) I noticed that I now got around 8l/100km when I used to get around 9l/100km before. OEM rims are super heavy, it seems changing rims & tires has a huge impact on consumption!

 

Its probably because your winter tires are rotating faster causing your odometer to show a higher mileage. I would reduce your odometer reading by about 4% and redo your calculations.

 

since it hasnt been mentioned yet and its simple: better air filter

 

Tune and driving habits.

With that you can improve the MPG a lot more.

 

Actually they're almost the exact same size, there's just a 0.3% difference. (0.2" difference in circumference)

 

You're right. I missed typed when i was doing my calculations. My bad.

 

You can program to lean it out a touch when at cruising speeds. Others have done this with some success.
