2. Keep your vehicle as light as possible

And Tornado's are crap... just blocking your intake and making your car LESS efficient. So are throttle body spacers.
If you haven't changed your O2 sensor(s) in a while... might be a good idea. Get/do a tune up while your at it... don't forget to change the fuel filter.
