Well I'm unsure of my results at this point. I did the extended boattail, underbelly tray finished and then an alternator delete.
Drove 200 miles at 75-80 MPG. Winds were 45-50 MPH, temperature 45 degrees and speed was 75-80.
I only managed 43 MPG.
With that in mind, I'm going to test the alternator delete to that effect first. If I reconnect it, and mileage isn't better, I'm going to look at the boat tail design with a true a-b-a test.
