High vacuum, better mileage, worse efficiency.
Low Vacuum, better efficiency, worse mileage.

That's the recipe for pulse and glide, engine on or off. P&G is using your vehicles mass to store energy. 10-20 MPG on the pulse, 150-infinity mpg on the glide, infinity when the engine is off.

Compression is the secret to efficiency. When you restrict the air flow into the cylinders by creating manifold vacuum, then your real compression is based on the pressure available to the cylinders. Your engine could create 10 atmospheres of compression, but with manifold vacuum of 50% of atmospheric pressure, your compression is half as much or about the same as cars 100 years ago.
