it seems as if our cars are quite sensitive...

i too have a proECM and in the city i'll get 18mpg too... but that is the dead city... around my parents home (suburbs) i get about 22-25

on the high way (after a bit of HW driving) i've got up to 30mpg

so the proECM did help... but not in the city

you may be ok
