I ordered my blue electronic vGauges boost gauge about 2 weeks ago and installed it. It worked perfectly until today. It was working fine, showing about -17-19 of vacuum and I shut the car off and ran and had some lunch with friends. When I came back out and started the car, it was locked at 209! It would fluctuate but never show boost but my Aeroforce gauge was spot on. I've never fiddled with the button on the gauge but am completely baffled as to how this could have just happened. The car runs perfectly fine, too. No stumbling, no nothing. Anything I can do about this or do I have to send it in?
