Re: Tach Accuracy
My factory tach was off in varying degrees across the whole range. I spot checked it like Tbone mentioned. After it failed I had it rebuilt with VDO internals and it seems to be real close but have not verified it. I'm thinking the tachs are like the other gauges, about, in the ball park.
