Wide-band Oxygen sensor, Google should get many hits. "Normal" range of mixture on a 930 can easily defeat a narrow-band sensor.

Innovate's LM-1 is a basic readout of mixture, but you can add boxes to log additional information like boost, RPM etc.

Zeitronix is another brand.

You can get a check/baseline on a rolling-road dyno, but this isn't the same as "real" driving.

Personally, I can't imagine trying to watch RPM, boost, AFR and traffic. So I think in-car gauges are bling, and think you need to log the results for later analysis. YMMV.
