Thanks guys

I stopped on the way today and took a few "money shots"

I do have that leading edge of the diffuser too low; I could not see it till I got it down on the suspension. I will raise it 0.5" and it will fold up behind the rear axle for 6" or so to insure it will not catch air.
I took some angle measurements and the diffuser was at 4.5 degrees. raising the leading edge 0.5" will get it right at 4.
I am on a 350 mile road trip today. It feels better in the wind, and seems to coast better/farther. I have no cooling fan, 75% of my radiator and grill openings blocked and the temps are good. I was just bumping into 190 F or so climbing a 4500' pass @ 45 F Outside Air Temp (OAT), Trans got to a high of 171 F. On the flats it is running 187 F and 152 F @ 60 F OAT. I have a 190 F thermostat in there.
Temps run up with the EGT. Cruising EGT is high 300-low 400's on the flats @ 60 MPH.

One really sour note: one of the supposedly "checked out" injectors is leaking at the body. I will be demanding a full refund
