Do people install vacuum guages to keep an eye on the overall health of the system? I realize vacuum and boost for power adders, but what about using them to simply monitor stock for vacuum leaks? Something like this:
A vacuum gauge can be used to help fuel mileage, yeah, I know, who cares about that when you drive a mustang right?
The highest vacuum reading when at speed, like steady highway speed, will get you the best mileage.
At least that is my observation.
Actually that's not really true, I usually have the 'go peddle' matted as often as I can
