<VV> new to turbo

[Mel Francis]

Not only did the turbo boost gauge verify that the turbo was working, but it 
indicated how much boost was being produced by the turbo. In the non-turbo 
version, the needle swung the other way, indicating how much vacuum was 
being produced, as related to throttle position and engine load. This is an 
indicator of fuel economy.
I have rented U Haul trucks equipped with a prominent vacuum gauge, so the 
user could use moderate throttle to keep the vacuum level in the green, or 
higher vacuum range, indicating better fuel economy.
