Yes, It could take much testing to figure out what works and what doesn't. Perhaps 55 is more efficient for long trips in which there's a lot of coasting and 45 is more efficient for short trips in which there's more accelerating than coasting? *Shrug* Unless I have more data than the few tests and little knowledge I have of the effects of tire pressure on FE, Comparing just a few runs is like walking in the dark.

*Edit, 2013-September-18: Is it like walking in the dark? Edited section ends after asterisk*

I do feel better about running it at 45ish in Moony so perhaps that has something to do with my increased MPG.

The bottom line, I guess, Is to just find what works best for you safely and without putting others in harm's way.
