Your going to have to follow this procedure..
1. Hook up Tech 2, turn car on, make sure module in the rear is plugged in. Do not unplug the rear module.
2. Use Tech 2 to delete the F45 option (F55 does not appear on the menu screen, use F45).
3. Save new configuration.
4. Do not turn car off, do not remove Tech 2. Go to the module in the rear of the car, unplug the grey connector (the widest one), leave any other plug(s) in. [leave the other 1 (F45) or 2 (F55) plugged in]
5. Turn off car, leave Tech 2 plugged in.
6. Remove remaining plugs from module in the rear of car. [never plug them back in again, if you do the F45/F55 turns on automatically]
7. Turn car on to verify the "max speed 80 mph" is gone.
8. Unplug Tech 2.

There are some smaller repair shops that have Tech 2s, or an equivalent. You should be able to call around and find one somewhere close to you. I would avoid the Stealership at all costs, and only use them as a last resort. I've found its hard to get out of a Stealers shop for under $300.00, no matter how small the problem is.......
