Really, how did you come to this conclusion?

 

yes give some of you scientific insight

i get about 240-250 miles a tank.

 

that gas mileage is awful, something is definitely wrong

 

Yea, i figured out that much.

 

i had an RS and i got about 18 to 20 mpg about 280 miles, rarely did i ever go 300mpg, but i did on the way to vegas

 

sorry to go off topic but can someone tell me how to go wingless and also what did u guys that are wingless use to cover up the holes in the trunk, if u dont cover it wont u get a lot of water in the trunk?thanks

 

Everything designed to be a wing, is not really creating drag, they create downforce or lift. That drag is too small to even talk about it. It most importantly does create downforce, wich is effect on your fuel economy.To notice that, you constantly have to drive fast. if you slow like 30-40 mph ,i really don't think you will able to measure that amount.
Even if you driving 80 mph ,most likely you will noticed the enviroment has more effect in your mph/gal then a wing. Example head wind or rear wind. Etc.

 

Please search, or start your own thread, thanks. I got a trunk of a Lancer ES

 

Take the logical approach you broke in your engine all wrong.

 

Not so much.

 

i want to take mine off

 

less drag... more mpg

 

^ exactly... makes sense to me

 

Changing gears at ~3500RPM? Perhaps some mistook the 4G63 for a diesel.

 

Put the spiked spoiler on the roof. Now, you will notice an improvement in gas mileage - if you drive 150 mph all of the time.
