On my old 1G I just used a Knock Box, which showed the current knock sum in LED. I only used a boost gauge when something didn't "feel right" aka probably a boost leak or some turbo system part failure.

If is pretty easy and cheap to setup an LED that warns of low oil pressure. On dry sump Evos we set it up so that we also require oil pressure for the car to be running, if oil pressure is lost then the ECU shuts the engine down. It takes a little extra cranking for the car to start, because it waits for oil pressure, we also have bypass buttons though. The main reason we do it on dry sump cars is in case the belt that runs the oil pump breaks or comes off.
