speedo out of wack

[troyza1981]

recently i replace my vs ss lsd diff due to stupidity anyways... the new diff is out of a vt ss and now my the speedo lies @ aprox 100 km my speedo reads about 130........ how do go about fixing this little problem?

I assume you are now running a different final drive (diff) ratio?
I believe you can change the PPK (Pulse Per Kilometer) input using a Tech1 to correct the error. Confirm?
