This is quite a mystery, I did a little drive last night, I often drive this route and have never gotten better than 40mpg, last night I got 42. It definatly is working...and I'm not getting any pinging or surging that is typically associated with vacuum leaks.

So if you're at max-advance, you should be making a bit more power, too, I'd presume. Except for the leaner burn, maybe. So maybe you just didn't lose any power?

I would have to wonder what would happen at this point if your knock sensor was still plugged in?! I bet that thing would be going crazy!
