Pretty sure it is hard coded in the firmware bin file of speedo. I know they have a separate file for Mach 1 assume it is the same for the GT500... may want to reach out to breeves directly....
Yeah, Doing some digging around here one person said his friends had it done to the Bullitt 180 but doesn't know what they did. lol
A UK thread said you need to reprogram the EEPROM I think that's what it is but it's very risky they wouldn't advise it.
I was pretty sure it wasn't easy to do. Just making sure.
