Gauge pods/Additions?
 

So I have an '02 R53 and have been looking around the internet trying to find out what the best idea is to add gauges. I'm stuck between buying two gauge pods and just adding oil pressure and boost, or buying one of those multi-gauge screens that lots of diesel trucks use, but I don't know whether or not the ECU takes those measurements. In theory, and this is theory, but if the ECU takes those measurements I should just be able to plug one of those multi-gauge displays and plug it in, right? All help is greatly appreciated.
