I'm in the market for a better boost gauge since mine doesn't seem to be reading very accuratly. Can you guys point me in the right direction because I have been reading different reviews on which is the most accurate and such. Either mechanical or electronic. I was looking into the Blitz BLM, but not sure if Mechanical is the way to go. I need a accurate reading boost/vac gauge for under 200 bucks and it cannot require a sending unit(like Defi) and it does not need to have a peak/hold feature. Reccomendations/suggestions welcome. Thanks.
