Just called Frank at Boca. He said all of these cars do that. I guess its just a built in screw up by Backdraft. I know my hot rod I built and wired does not do that. Wish I knew what your guy did to fix the problem. I am going to install new Smith gauges this winter and the water temp and
oil pressure are manual. This will correct that problem. I guess I need to rewire the gauges.
