I have a whole pile of mpg numbers, but nothing from the wheel covers or partial skirts yet. My mileage started out around 28 mpg, driving technique took me to about 33-4. A lot of my mods have gone on sort of overlapping so it is difficult to tell exactly what mod is giving which improvement though. My last few tanks have ranged from 35.6 to 38.3. I do a lot of highway driving, but there is a varied mix of city driving in there as well.Hopefully these new mods will show some gains.
I should also mention I have done more than just aero mods, I have also removed my power steering and AC, and have a warm air intake and relocated IAT sensor that I am playing around with as well. Tires are at 44 psi as well.
