I was thinking of buying a pillar pod for some aftermarket gauges and found a triple pillar with 3 gauges. One of hte gauges it came with was a vacuum gauge. I got to thinking, why exactly would one want to know what the vacuum pressure was at? Anyoen know?

I got a autometer Vaccum Gauge, It reads Throttle Postion, and Load on Motor. Mine Reads about 23 At Idle.

a vacuum gauge can be a very valuable tunning and diagnostic tool. a vacuum reading can tell you alot of whats going on in your engine. ie: late valve timing, late ignition timing, stuck valves or lifters, burnt valve(s), intake leak, blown head gaskets and many more.

if your getting the A/F gauge get the wide band that needs to be placed at the midpipe
