A/F meter vs EGT meter
To those with both the A/F meter and EGT meter, they both pretty much do the same thing: tell you if you're running rich or lean. So why have both? They look cool, but they aren't cheap, so I'm trying to figure out which to get.
Thanks,
Thanks,

Cheaper a/f meters aren't nearly as accurate as a decent EGT probe. This is what I'm gathering here on the .org. So unless you invest in an expensive a/f, I would probably forgo that one and add something else in it's place. Fuel press, oil press, oil temp, water temp or whathaveyou

Go with boost and EGT. If you want another one, go with fuel pressure. If you want an even number, go with oil pressure. If you want a number divisible by 10, get a water temp gauge.
Do you see the snow ball effect? Hehehe

Just kidding.. I'll just have the three on the A-pillar. I already have a boost gauge, and it looks lonely all by itself on the A-pillar.

I'd go with an electric Fuel Pressure Gauge and an electric EGT Gauge, which will probably require the separate purchase of an EGT Gauge Probe, about another $100. If you get Autometer Ultra-lite gauges from Summit, that'll come to about $400 or so.
Don't get mechanical gauges for the inside of your car. These require you to run hoses/lines inside the passenger compartment. No good. If you install electrical gauges, only a thin wire runs through the passenger compartment to the back of the gauge. That's good (& safe).
Cheap A/F meters only provide a light show. They are not quick nor accurate enough to do anything but. Good A/F meters come with their own broad-band sensors, and run $400+.
If you had *good* gauges for both EGT and A/F, you would have a redundant safety system to ensure your engine does not run too lean. If you were enjoying the benefits of an *expensive* boosted engine build-up, you might feel a redundant gauge set-up was well worth the added investment...
Good luck.

Thanks for the information! Lots of it too.
I plan on getting the Autometer Ultra-Lite EGT meter with probe, but the one with the probe is a mechanical gauge. The EGT without probe is listed as an electrical gauge for about $10 less. Weird?
I also plan on getting an oil pressure or temp gauge, and a tranny temp gauge.
I don't really see the need for a fuel pressure gauge. What can you tell from it, if you're leaking gas or something? Sorry.
I might also get a new boost gauge that has PSI measurements instead of bar. My Greddy boost gauge shows bar and it's hard to see how much boost you are running.

Go with the EGT gauge, unless you buy a Tomei or Greddy A/F gauge.

Nitrous pressure, fuel pressure, EGT, and .....?

The Greddy and Tomei look good. I still prefer the look of the Autometer, but it's not worth it if it's not accurate.
So what's a good reading on the Greddy look like? 8, 9, 10,...?
