I think he's talking about the vacuum guage between the heater vents. There's two gauges and pretty sure they only come on premium trim.

This is a joke right? Troll? Why do you want a boost gauge on a NA car? I'd work on getting a supercharger/turbocharger before worrying about a boost gauge. WtF??
