Cons of Boost Guage with no Vacuum

[TurboFever]

Well I just installed my boost guage yesterday, and found people prefered guages that read vacuum ( 10psi in hg or w/e) but mine doesnt, what are the cons of having one that only reads from 0-30 if any?

the only con I can think of is now you need a seperate gauge to read vacumn. I personally like having one for dedicated vac, and one for boost. Knowing your vacumn at certain times (idle, cruising, etc) can help you pinpoint problems. (I.E. Vacumn leaks)

I have an autometer with boost and vacuum and i love it. Knowing what your vacuum is at idle/cruising/deceleration can be very helpful, it will let you know if something is wrong with your car (boost/vacuum leak, incorrect base timing, valves, ect.).

Also, VAC is measured in INCHES of HG (not PSI).

Via one gauge or a pair, ensure that you've got both sides of Zero being displayed. It's too vital to basic comprehension of your car's condition to go without.

One vac/pressure gauge = one place to flip your eyes to while driving, only one gauge location filled, one tube to tap in and route through the bulkhead.

There's not a lot going for having two gauges to do what one can do seamlessly.
