unsure on gauges

Ok, i'm getting a boost gauge of course. Now my friend says to get a fuel pressure gauge(electric) and then to get an a/f if i want to, but its more of just a light show.

Now i did some searching and it seems people have oil pressure gauge and egt gauge. Are those really necessary?

Basically, I want to get the gauges that i would need most? I'm more than likely getting a triple pillar pod.

And i should go with the autometer pro comp lite series gauges right, i've read that they match well?

stewart warner maximum performance gauges, bling bling. From the sound of it, the only guage you'll really need is a boost gauge, get the p5online gauge pod and be done with it. Also you wont have everyone trying to race you cause you have visible gauges.
