This topic may have come up before, I don't know. If so I'm just bringing it up again, there's always new members with new input on any subject.

Gauges: Which gauges do you NEED, and which gauges are nice to have? Which gauges are unnecessary and which are completely worthless?

Obviously you need a boost gauge. The new profec b spec II and a lot of other electronic controllers are starting to integrate a boost readout. So you could probably get away without a gauge if you had one of those. Still, isn't it a lot easier to monitor a gauge that's either on the a-pillar or somewhere on the dash/around the instrument cluster? It's nice to know what's going on with your boost second by second. I think I'd still keep a boost gauge even if I had one of those electronic controllers.

Other than that, it's not set in stone. EGT is usually 2nd, but not necessarily, then you've got water temp, fuel pressure, oil pressure, wind speed and barometric pressure ( ) and enough other gauges in this line to fill every available mounting location. Then you have the dreaded a/f gauge. There are also aftermarket tachs and shift lights and such, not all of them of the 5" monster variety, as well as devices like the rev/speed meter.

What's your personal preference when it comes to gauges?
