Speedo converter reversal

[ELA]

Hi guys, the car I have just bought has a 180kmh speedp but has been converted to MPH. How can I reverse this process; if I take remove the cluster will it be obvious/do I just cut the wires to a little box???

It will be obvious, its a little box or wrapped up chip with four wires coming out.
The car will now be speed limited unless you have an Apexi.

Many thanks Philiwily, I do have an ApexiPFC. I guess I can just cut the 4 wires and it will revert back to Kmh and with the ApexiPFC fitted the speed limiter will be removed i.e allow V-max as apposed to only 112mph?
