Disabling aftermarket speed limiter on F-250

[Woodsnwater]

Good afternoon. I recently got a 2021 F-250 6.2l. It has an after market speed limiter I'm assuming is programmed in to restrict it to 65mph. I would like to remove it but don't know where to look. I don't want to change the factory max speed. I disabled the mykey feature but it didn't do anything. I've seen other people say they reprogrammed the keys on other makes and it remove the aftermarket speed limiter. The 65mph is kinda stupid considering most highways max speed is 70mph and cruising is usually closer to 80mph.

You sure mykey isn't still enabled?
