The stock boost gauge get's it's signal from the big signal sensor on the BOV assembly (red circle..see next post below), so it is electronic. Most, if not all, aftermarket boost gauges run on a vacuum/boost line, non electrical.

I would recommend you also check the overboost switch connection on the BOV assembly (yellow circle..see next post below).
