hey, had a question for all of you. a boost gauge vs. a boost/vac gauge, just wondering on what's the difference and if i really need to have a boost/vac gauge because all i really want to measure is boost. so i don't see what's the point of having a boost/vac gauge. so if anyone has any advice or good points on which one to get that would be greatthanks jeff

vac can be a good indicator of how your engine is running. its just a nice thing to know.

Get one that measures vacuum as well. Your engine spends significantly more time in vacuum, than it does in boost.
