Disclaimer: this test was run using old data for the "A & A2" sets. i did this because the bolts holding on the cover (where mirror was) are not assessable and the epoxy I had placed there to keep them from turning did not hold. I can take the cover off but I will ruin the threads on the bolts to do so. I decided to not hassle with it. The testing conditions from 2 weeks ago to today are very close. it is the same road, speed, and start stop locations. the only change is the wind (5MPH from the east today, was 5MPH from the NE last time). This was a minor enough change that I trust the data. The MPG gain is 1.6 or 3.72% gain. It might not be quit that high but will still be over 3%.
