Re: How accurate is the stock tach?
It pulls good all the way to the shift points.
No complaints with the performance, I just know
that the stock cam is not much good past 5500.
I knew it was off, just wondered if it was a common thing with these cars.
I may send it off and have it calibrated.

Re: How accurate is the stock tach?
Typically, they read 100-200rpm higher than actual enigne speed, and in extreme cases 400rpm. Since the stock rev limiter is set for a bit over 5,800rpm, yours would have to be reading 700rpm high if the car is truly "bone stock". Never saw one off that far.
