Only thing I have done so far is up the pressure in my tires to 45 psi and work on my driving style. Taking off slow from a stop ,trying to keep the RPM's down as much as possible and cleaning all the excess stuff out from the car is all I've done so far. And to add in I just got back from a 326.3 mile trip where I stayed between 65 and 75 mph depending on the semi truck in front of me and shattered my old record mpg. When I filled up I got 30.725 mpg and I still had 5 gallons left in the tank which would have got me 460 miles out of one tank had I kept going at that rate. I'm looking into getting/making some smooth covers for my rims and making a upper and lower grill block soon for my first mods. Oh and I still have an O2 sensor throwing a code so I'm sure that's not helping things any.
