General Buick Tech / factory tach/boost unit

Hi all
My factory tach has gone haywired... and probably needs to get re calibrated.
question... if the factory tach is bad, does that also impact the factory boost gauge. I am trying to figure out if the factory boost gauge is still working properly or not... or I may have a vacuum leak somewhere. With just a light throttle, 2 or 3 bars light up on the boost gauge... but nothing moves on the aftermarket gauge.
I remember with a vacuum leak, the factory boost gauge would light up pretty quick with any sort of throttle response... but I can't remember if the needle also moved on the aftermarket boost gauge.
thanks... dave
