I think you are on the right track with the 16.5:1 air mixture. Have you tried higher to see when you start getting knock? I believe Honda had 22:1 but this was on an engine that was designed around that idea.
Can you have the higher air/fuel mixture only kick in under certain conditions? Cruising only. Turn off when you step on the gas pedal.
Who much control does the Megasquit II give you?

I plan an extended cruise soon with a friend to play with the timing. The strategy, when a dyno is not available, is to advance timing until the detonation gauge begins to light up, and then back off a degree or so. With a dyno you look for max HP, but sadly I do not have one. All the ones around here are not steady state dynos, which is what is required to set timing for cruise. Read above post for description of tuning capabilities of Mega Squirt.
Thanks as always for advice and ideas.
