Why did Porsche even bother installing a dash panel? I guess it was for the tach, because we need to AVOID certain rev ranges, like anything below 2000, 2200-2500, and 2700-3000. Especially 3000! 
Sorry to vent, but I'm just sayin'..............

No, it is quite common. All OEM's set their speedo's to read 4-5 MPH higher than the car is really moving, supposedly to prevent lawsuits over speeding tickets, but in reality it probably has more to do with running the odometer faster to run out the warranty sooner. There was actually a class action lawsuit by Honda owners on this subject when it became common knowledge that most Honda's were off by over 7 MPH, which shaved months off their warranty coverage.
Same nonsense applies to dash gauges, very few are accurate in other makes either.
You want accurate gauges, go aftermarket. At the end of the day, just remember that you are discussing what temperature the car is when the dash says "180"; the reality is that none of these cars, unless they have an aftermarket thermostat in them, has a prayer of actually being at 180 when the dash says it is.............
