Boost Gauge vs Boost/Vacuum Gauge

What's the difference? and why would you run one over the other?

Supercharger = Boost?

Turbo = Boost/Vacuum?

I'm mostly curious :dunno:

On my GTP I have Boost/Vacuum.

It's better to have a Boost/Vacuum gauge regardless which FI you have. You want to see at what rpm the motor is referencing the amount of vacuum or boost. Gives a wider scope of motor efficiency versus just looking at boost.

Nicely put, I agree with getting the boost/vac as well.

does anyone have pics of how they tied into their sources for the boost gauge?

I went with an electronic boost gauge that utilizes its own map sensor. Why?

Well,

- I don't have to deal with running a line into the car
- much more accurate and faster readings (shows instant boost spikes)
- adjustable warning light
- records peak boost
- can be data logged
- and the cool factor!

I'll try and get a pic.
