One could argue why run a boost gauge then? Who's looking at that gauge while driving hard? I run a Cravenspeed steering wheel mounted dash pod. I only run the left cup as it covers the mechanical speedometer (who looks at that one compared to the digital one in the center?) and use a 60mm Depo Racing 2 in 1 gauge. It reads boost with a needle display and displays oil pressure on an led display.
I figure if pressure drops suddenly the fast swing of the numbers will catch my attention if I'm on it hard.
But to each their own.

These are the only thing that "may" save "some" of your engine in the event of lost oil pressure.
Gauges look groovy, but as stated, when your balls to the wall mid corner, the last thing your going to look at is your gauges.
BUT, a big red light high up on your dash is something even the most possessed driver will see.
15-50 psi

The one I had in my Skyline worked a treat, once I painted it black, leaving only the small circle of red in the middle of the light, at idle the light stays on, mine was set to 30 psi IIRC, the time it did go off, mid corner at Wakefield Park, was when the RB spewed all of it's oil out of the head, into the catch can and finally onto the track.
The engine was saved miraculously, and I proceed to thrash it's guts after cleaning up, working out that I was an idiot, then refilling the oil.
It turned out the drain back line to the sump from the catch can had kinked after I took it out to clean the internal filter (stainless steel pot scrubbers) with some metho.
TL;DR bright light
