Really Dumb Question

[fiveotony]

OK I have a auto meter sport comp tach and my stock one my stock one says I am idleing at 1200 RPM the auto meter says around 850-900 which one would you believe????

Auto meter without question.

You would be suprised. I have heard of stock tachs being off as much as 500 rpm in the upper part of the rev range.

 

[fiveotony]

me too but never really on an idle. maybe the stock tach is a POS???

My sport comp says the car is idling at 975-1000rpms and yet the stock ones says 750-800rpms. I can tell by the sound that the autometer one is right.

yeah id put my money and your money on the fact that the autometer tach is correct....stock equipment is garbage!
