Hey everyone, I had recently acquired a boost gauge for my LNF (mine has the RPD) so that way I can watch speed and boost at the same time. Anyways, it is a Prosport Premium Electrical Boost Gauge, I have everything wired up right (except it stays on indefinitely, I'll fix it later) and the hoses right as well. Except the gauge reads -9HG with the key on Engine off. Drove around with it plugged in and boost was off about 5-6 PSI. Is there a way to fix this or am I going to have to scrap the gauge and buy new ones? Any input is appreciated
