All-righty, if your speed was reading slow, the Tire Size (TS) you were using before was a bit too small. An error of 2mph in the 70mph range is in the 2-3% range. IF you were using 2560mm before, you'd increase that to 2611 - 2637mm.
My guess is though, you were not using 2560 earlier, but had entered something smaller? AND, when you enter the TS, also make sure the Gear Ratio (GR) is correct. The older Gryphon uses "placeholder" values for both TS and GR in the Custom Options menu, and BOTH of them can be wrong.
