I'd either do a Boost/Vac Gauge and an Oil Pressure gauge.... or a Wideband Gauge and an Oil Pressure gauge.
Boost/Vac has its uses and importance but when compared to a Wideband and Oil Pressure without fuel and oil you have no motor period. Thats my take on it.
In my GTP I have a Triple Pillar with Oil Pressure, Volts, Boost/Vac...... I have a LC1 Digital Wideband gauge and L67 Scanmaster in my cluster. Not to mention an ICCU in the center console cubby.
My black GTP has just an L67 Scanmaster in the cluster...
