You would see the biggest gains from grid charging, but the intelligent alternator control you describe is better than stock.

You could have the brake lights drive a relay that turns the alternator on, which is pretty much what I have in my Insight.

I'm curious: How much does your gph at idle rise when you increase the load on the engine?
