IMO dump the afr gauge, and run oil pressure, oil temp, and water temp. I think those are the most important gauges to have in a N/A car. The only reason you would need an afr gauge is to tune, but then again they aren't that accurate, and you would really want a wide band o2 sensor instead.

A simple search for "gauges" would yield so many answers that you wouldn't need to post anything.

But, for monitoring and making sure things are working correctly, oil temp/pres and coolant temp are ideal. For tuning, add EGT, a wideband A/F, fuel pressure and manifold pressure gauge. If you have an auto, toss in a temperature gauge for the ATF. That will cover all bases at the very most.

Most A/F gauges are just a light show or bouncing needle. All I've ever gleamed from it is when I need to replace my O2 sensors. Real tuning is better served by a wideband unit.

While it's true that there are piles of threads discussing this topic already, a better search than "gauges" is probably "which gauges". I've been working on this lately, as well. EGT and oil pressure appeal to me, and I haven't determined a third yet. I need to do some more ing.

Blast, and here I thought I was helping.

The breakdown of gauges and jobs is something like this;

Oil Pressure: Is oil still in the engine and is the system complete?
Oil Temperature: How hard am I working the engine and am I within the oil's operating limits to avoid breakdown of the oil?
Coolant Temperature: How hard am I working the engine and is my coolant system ensuring things continue to operate smoothly?
Fuel Pressure: Is fuel getting to the engine's cylinders so they can fire? Am I getting enough fuel to the engine?
EGT: Am I running rich or lean? (lean has a hotter temperature)
A/F: Do I have the right mixture in the cylinders to provide optimal output? Best determined by a wide-band O2 sensor as it will be provide more accurate readings.

As I mentioned, normal drivers probably only need gauges for oil and coolant. Tuning brings the rest into the picture as you need to determine that all 4 cylinders are at optimal performance.

Mainly, it is up to you how much you want to spend and how much information you want to know about your car as you drive it. Me? I have 7 gauges, as I am an anal retentive bastard that likes to know EVERYTHING about how the car is working.
