I have a triple gauge pillar to fill and I want your opinions on which gauges are the most useful to get. I'm pretty set on a voltmeter, but can't decide about the other ones. Others i'm considering are air/fuel. oil pressure, oil temp, water temp (any others?)....I just want to know what you guys would recommend.
TIA
Oil pressure and (if you can afford it) wideband 02
definitely oil pressure...
