I got about 27mpg average on a 1400 mile trip.
I had the mirrors folded in, added about 2mpg.
Up-pipe, downpipe, k&n drop in, light flywheel, JDM STi 6MT, COBB stage 2

I got about 26mpg on the way back.
But I added STi pink injectors, and a VF 34, with the COBB VF 34 map

This was all interstate driving at between 80 and 85 until the last 250miles, then it was highway and twists through AZ

Are you telling me that by simply folding your mirrors in you gained 2MPG? I don't mean to bash, but c'mon, how is that even possible? There's better things you could do with aerodynamics that wouldn't give you as good as results (ridding your hood scoop, etc.).

I'm getting 2 more mpg better now that I'm untuned, on the highway though its stay about the same untuned vs tuned. Or maybe I folded in my mirrors...
