The boost guage seems to be reading accurate but the tach is reading about 3000 rpm at idle and its not idling nowhere near that.Just thought someone might have an easy fix
I'd also like this info. Maybe poor connection someplace. Mine always seemed to read at least in the ballpark but after redoing all the harness and dash removal during the restoration now the boost and tach always read much higher than before. It;s about the only major glitch I've run into with this project. Blowing the motor on the dyno doesn't really count.
