It would be my GUESS that wheel weight would matter 0, or almost 0. Also, look at our runs, they were +/- 5HP each time, so 7 is only slightly above this noise. And there should be a few HP in engine oil alone, maybe you're running a heavier oil than he was? For example:

They showed 7HP difference in oil alone (and yes, they're trying to sell a product, but from what I understand their findings are on par with others)
