I bought and tuned up a 92 VX with 233xxx miles on it. I put brand new tires on it which are the correct size at 40 PSI. brand new o2 sensor, the correct spark plugs/wires, cap and rotor, all new seals, factory intake with new filter, new brakes...yadda yadda yadda. I am a honda guy and i am very familiar with theses cars but I cant seam to get past the 40ish MPG range.

I drive this car 60 miles one way, mostly highway to work everyday. Ive put 3200 miles on it all averaging 41 MPG.

How can I get this this to do better? am I missing something? It does go into lean burn mode, I can feel it but I have no instrumentation to watch
