I found a good road to do some testing. I drove around for 40+ miles for work before this. All highway, all 60-45 P&G,
Engine coolant only got up to 147*F
Air intake temp was 67*F
I set the cruise control for what my GPS recorded at 55MPH

It is a 4 mile two lane road with a 1 mile long lightly traveled bridge with a tree line on each side.
Very Quiet. Weather was 50*F 0 rain 0 wind 0 traffic
ScanGauge was spot on last tank so hopefully the numbers are correct you see here#!

I did 10 runs 5 north 5 south. I sped upto 55 MPH hit cruise, as soon as my front tire hit the bridge I reset the Scangauge AVG and wrote down what it was as soon as my front tire hit the other side of the bridge.

It had a slight bump so it was easy to look at the scangauge at the correct time..

North: 42.4 43.5 45.6 44.2 45.3
+
South: 41.4 44.7 42.2 43.2 41.7
=
434.2 / 10 = 43.42

So my KIA gets 43.42 MPG at 55MPH in the "stock" form it is in now.
All of my upcoming Aeromods will be judged against this number.

Awesome#!

And My speedo is wrong when compared to GPS.
IT shows 57-58 when GPS is on 55-56

Can anyone help me do the math for what my odometer should be reading?
