Vacuum gauge

What is the use of having a vacuum gauge?

keeping the engine at maximum vacuum saves fuel. Its a way of making yourself stay out of the skinny pedal.

x2 i got one and it works. when haullin the big trailer. i figured it was good in top gear. but installed the vac gauge and found out it was bad . no vac in top gear. drop to a diffrent and bam perfect.

play with it a bit and also find that to cruise you dont need as much pedel to stay the same speed as before.

A Vac gauge can tell you a lot about how your engine is running as well.
