Ok I might get flamed here but are they different gauges or are they one-in-the-same?

Engines naturally have a vacuum, so most boost gauges go from vacuum to boost.

They are normally built into the same gauge. Here is an Autometer that I've got on my Supra:

Thanks for the replies, I'm wanting to keep and eye on my vacuum but wasn't sure if it was boost gauge or a specific vacuum gauage I should be looking to purchase.

If you don't boost then just get a vacuum gauge if you want to see a wider sweep.
