More ado about the 996 speedo

My 996 speedo reads 3 - 4 mph slower than the speed indicated on my GPS or on radar speed-limit signs. My Cayenne always matches the GPS and the sign readings.

I think most of us would prefer accuracy across the board. I know years ago, speedo shops that tested police vehicles would simply change a gear in the tranny to adjust the speed if it was off, but obviously everything is based on electronics now.

In the "Things you didn't know about the 996" thread, there are conversations about this issue. The consensus is that the offset (~3 mph) was a Porsche decision to comply with German laws that forbid under-reporting of speed, and this can't be adjusted. You can find the unadjusted speed (in KPH only) on MK-I cars through the Climate Control display.

Possibly a little known fact here is that the accuracy of the speedo can tweeked by the dealer to make it accurate. This was a topic of discussion in '97 or '98 on PPBB the Boxster forum. I had my '99 Boxster at the dealer while still under warranty and had them adjust it. I then checked it against my GPS and it was 100%.
I never did my C2 or the Turbo.

can anyone tell me how much of a wet dream is the idea of a 200 mph gps speedo
seated in it's proper place inside a 996 guage cluster?
I've got a nice one available from speed hut, but it would complicate things,
as it would have to switch positions with the tachometer to do it.
not exactly what I had in mind.
