See how your speed isn't going up in a linear fashion, basically the software is "guessing" your speed when the GPS isn't updating.
Also the more I think about it, are you sure the speed is right? I don't know how modded your Z is, but 129mph down the backstretch needs a lot of HP or crazy cornering speed up the esses.
Is the 129mph off the GPS or off the OBD? It would make sense if it is off the OBD since the speedo on our computer reads a few mph quicker
