It's been long enough with two dead gauge heads so now I need some ideas for what to get to fill the third hole in my A-pillar pod since the other two will have a ScanGauge and a boost gauge (pyro is on the steering column). My boost gauge is a DiPricol Optix series so I'm leaning towards the electric Optix 0-100 psi fuel pressure to match it but if there is a more important input to monitor (that the ScanGauge won't display or will display but with the hassle of extra add-ons/sensors) I'm open to suggestions. I would prefer that the gauge head be either a DiPricol Optix or close in appearance to match what's already there.
