lol this might sound kinda stupid. . .ok it does. But theoretically, could you take a tire boost gauge and hook it up to your vacum line to read the PSI?

Yeah, but I doubt it would be very accurate. This also begs the question, why?

Yea, not a good idea. I mean Autometer mechanical boost gauges are only $50. Just use one of these.

well i just got my autometer boost gauge and dual pillar pod in the mail. But it was just an idea of mine, i wasnt going to do it. Does it look that bad that i have a dual gauge pillar pod and only one gauge right now? I got the pod and gauge as a xmas present and right now money is really tight.

Consider it planning ahead.;)

Even though I'm not particularly a fan of pillar pods, I totally agree on the planning ahead idea. Everybody understands the not having money problem!
