Saw as high as 49.8, sooooo close to my 50mpg trip target! Did more engine on pulse and glide, let glide extend much longer when traffic conditions allowed. My recent aero mod is definitely helping.
Here is the latest mod, a partial box-cavity, didn't have enough time to make the sides.
Tank average sits at 39.4 right now, lets see if I can bump that up to 40.
EDIT: Turned out to be 47.1 MPG
