Saw some positive stuff about this "ultragauge". It was just what I was looking for not really into the pillar gauges and it can show a lot of info at once with the big screen. Probably gonna mount it with the included windshield bracket to the left of the speedo. Price point is excellent as well and just plugs right into the OBD II. Simple just how I like it.
Should be able to monitor my fuel and boost pressure. One thing I really like about it is that it will give me instantaneous MPG which I find a useful tid bit of info.
