You would be surprised. A good one is a reminder of what you are doing and 
how well the engine is performing. Of course to be meaningful it must be 
readable unlike the Corsa boost gauge. Am thinking along the lines of a 
Westach 2C4-3 (black face) http://www.frostalarm.com/cat/p3.html or maybe a 
Pontiac chrome bullet.

Is particularly useful in tuning - at any given speed, the higher the 
vacuum, the higher the MPG. Only thing better is a real instantaneous MPG 
readout (Accucomp, Prince). Once you learn how to keep it at a maximum as 
much of the time as possible you will be amazed at the difference.
