Sounds like the perfect candidate for lean burn.

I could see peak BSFC being better at closer to the manual's RPM maybe, but every BSFC map I've ever seen is "wide" rather than "tall", which is to say even if peak BSFC is at a higher RPM, you're still better off with higher load and lower RPM.
I think you're spot on with the lean burn idea.
That's coming very soon in my Insight, I nearly have my fuel maps clean enough.
