restoring factory economy to honda civic vx

i have a 92 civic vx , the fuel economy is about 32.5-37.5 with a 5 to 1 city/highway , i would like to get this average to about 38-40 ala factory specs

since i bought the car last winter have replaced

- new oem fuel pump
- new oem fuel filter
- new braided fuel line
- cleaned and remapped oem fuel injectors
- new oem fuel regulator return valve
- new oem spec ngk spark plugs gaped perfectly
- new ngk coilpack/cables
- new distributor
- new oem timing belt
- new oem water pump
- new temperature sensor
- new ecu
- new oem iacv
- new battery
- new axle back exhaust
- new intake filter
- new driver side axle
- throttle body thoroughly sprayed with throttle body cleaner
- tires 42psi+
- egr "scraped" new gasket

even with all these "refreshments" i can still feel the power cut out or "sputter' for a mili-second when cruising at highway speeds i feel like this maybe directly related to my lack luster economy

the 02 censor looked brand new when i bought it , the only thing i can think of that i havent replaced yet

- egr
-cat converter
-new front brakes and wheel bearings to reduce rolling resistance

if there and any other suggestions for things that i missed to get my fuel economy where i want it that would be much appreciated....
