The A-B-A test done was flawed.

Yes it would help Dave and welcome to ecomodder.

The 4% gain Fubeca determined through an A-B-A test on a cold day, under 20 degrees with a strong cross wind, is flawed.

Fubeca agrees it is flawed in this post in another thread:

The mystery is why, on a webpage which heralds correct data and testing methodology to arrive at a figure for fuel economy improvement, this thread remains front and center on the ecomodder home page?
