Unofficial first results:
2.76 gallons consumed over 59.3 miles -> 21.5 MPG average
90 degrees F outside/140 degrees intake air temp
A/C on
average speed 64 MPH
Now, some problems I've noted:
Going straight and level produced most of the MPG gains. Compared to my previous throttle, though, MPG suffered more when going up inclines. For instance, there's a stretch of road about a mile long that is about a 2% incline. With the old throttle, I could expect to see an instantaneous MPG reading of about 18 MPG on the overhead display, corrected to about 16 MPG actual. With the wedge in place, I saw 15 MPG on the overhead display, corrected to 13.5 MPG actual.
I will have hard numbers tonight, on my homebound commute.
