I had no idea gauges were so expensive.
So with my motor swap I figure a Boost gauge is almost an absolute must have.
I'm not sure what else is important. I only really want to add 3 gauges. I don't want my car to look like an airplane cockpit.
What really is the benefit of the fuel pressure, or oil, EGT? I figure a nice voltmeter would be nice. It is one gauge I would have really liked when my Alternator died.
If you had to choose 3 gauges, which would you go with?
