I recall passing them at 63. If I had a faster governor. More or less.
FFE was governed secretly at 63 while the Speedo showed 65. Laptop GPS busted this wide open when I submitted that to be recalibrated. I used to deal with swift, marten etc when my rig was close or at the same governor.
They may or may not have changed. This was like 16 years ago in my time.
