Modding For Better Gas Mileage?
Everybody's going after horsepower, torque, handling, sound and looks.
How about going after better gas mileage? What works?
Here's one I can think off of the top of my head- even if it's something most of us wouldn't do.
Skinny, over-inflated tires. Seems like when most of us goes to a 7.5 or 8" wide wheels, our gas mileage drops by about 50 miles per tank.

YOU HAVE A FREAKING SPORTS CAR WHO CARES ABOUT GAS MILEAGE!!!!!! lol jk:banana:
lets see adding an exhaust system and adding a more efficient flowing air filter most of the time gets better gas mileage, not by much though. Things that let the engine run more efficiently helps gas mileage. The best mod probably would to put like a brick under the gas pedal so that you can't slam it down and go fast lol. Well that's all I have to add to this.

Hey, that brick under the gas pdeal idea is GREAT, Raymond. 
Letting the car breathe better via intake and exhaust would help a bit. Here's a few small things that would also help, using a quality snythetic oil to reduce internal friction would also help I would imagine. Also making sure the spark plugs are clean, of the correct type with correct gapping would help as well. Keeping heat away from the intakes will also help.
I seem to remember something being said about putting 87 octane gas in there and not having knocking problems by having the computer re-program itself to run on that gas? This wouldn't help gas mileage I don't think, but would help save as much as 4 or 5 bucks every time one fills up their car. Besides lower octane gases burn faster than high octane gases. Anybody know about this or how much power loss there would be, if any?

Would getting a lean map for light throttle settings cause premature motor wear due to the overheating of the cylinder walls?

Think of rolling a bike tire around a corner. Pretty easy, very little resistance. Now try to roll a dragster rear tire around that same corner. Probably aint gonna happen because it requires more power to move that big tire. More power means more gas in the engine. Thats an exageration but you get the idea... I hope

You probably wouldn't like driving a WRX with zero boost. Its low compression necessitated by the turbo would mean sluggish off-idle response and with no boost it would also be weak throughout the RPM range. An RS2.5 would eat it for lunch.

Wingless, don't have a WRX yet, still shopping which is why a vehicle isn't listed in my profile.
Increased rolling resistance and weight are two out of the three reasons why a wider tire would result in worse gas mileage. The third would be aerodynamics. A wider tire pushes and drags more air as it rolls down the street. Take a look at a Geo Metro or a hybrid gas saver car with super aerodynamics. Skinny tires all the way, baby!
