I have my boost gauge tapped into the map line pre boost fooler and it reads correctly as far as I can tell. I also have my Livewire which has it's crappy gauges too. The livewire reads boost that the MAP sends to the PCM correct? At an idle the livewire shows a negative boost PSI, and always has, usually -2 to -3 PSI. Does this seem right, that the MAP would be seeing a vacuum at idle? Watching both gauges I almost get to 5 PSI on the actual gauge before the Livewire reads 0 PSI. If it isn't normal what does it mean? I've checked for boost leaks and can't find any.
