As gas get closer to $4.00 a gallon what mods have you guys done that have improved your performance AND gas mileage?

Drive a 4 cylinder.

I use the "stay out of the boost" mod, it works pretty good

5th gear + cruise control as soon as possible.

Any thing you do to lighten the car will help.

All I can think of is the obvious, like tire pressure, and proper maintnance. As much driving as I do I am thinking if it would be more cost effective to pull my tune out so I could run 89, and or filling with 89 and adding octane booster. Also what kind of milage improvements you guys getting after adding bolt ons like cai and pulleys. Currently I am getting 24mpg.

untuned for my engine, and running rich as shit I got 19 mpg last tank, all highway, and a whopping 14 the tank before of all city driving. lol

Drive a 4 cylinder.

LOL Civic for the win!

(But I really am going to miss my Mustang this summer! :cry: )
