H2 top speed?

[Gunzz]

There actually is not a governor but there is a top speed control built in to your computer that controls your motor, transmission, speedometer, etc. Unless you go to the dealership, you'll have to buy a programmer to access the computer and tell it to allow higher top speeds. 80 to 85 sounds low unless you have after market tires that are larger, causing the computer to go out of whack.
If the tires are larger, then the computer needs to be reprogrammed with a programmer, to make the changes. The programmer is a small handheld device that plugs into your vehicle under the dash, very simply. I use the Diablo Predator, but there are others available.

Hope this helps. Good luck.
