Vacuum / Boost Gauge?

[Detroiit]

My buddy gave me a auto meter boost gauge but it don't have vacuum on it. Do you all recommend the vacuum/boost gauge or will the boost only gauge be fine? Its the Auto Meter 5704 boost gauge.

It really depends on what "you" want to see. Mine is a vacuum/boost gauge but I'd be just as happy with a boost only gauge.

Well if you are running a power adder then you only need the boost gauge.
