Get yourself an MPGuino - it'll help your driving SO much. It also works as a lean burn indicator, since your instant MPG will jump up noticeably when you enter L.B.

It's load based. So it's possible you're feeling it at lower speeds and in gears other than 5th.

3)Since lean burn allows a lot more air into the system

In lean burn, air consumption stays about the same for a given power output. It's the fuel input that drops. If your VX is like my Insight, you
may have to open the throttle very
slightly more to maintain a given speed when you enter lean burn, which would show up on your vacuum gauge.

4)Hills .... If I don't want to drop below 60mph, should I "floor" it in 5th or give it a little bit of throttle in 3rd.

An MPGuino will answer this ... and will tell you to stay in the highest gear you can.
Also: MPGuino, MPGuino, MPGuino.
(Big fan of instrumentation. It's invaluable.)
