Nope x-2 don't correct speedo, the rev per mile is for correcting the shift points for trans.
It's best to manually measure your tires and calculate rev per mile.
Tire Revs Per Mile
You can have the dealer correct the speedo thru the OBDII or you can buy Autoenginuity to correct the speedo and have a decent diagnostic scan tool to help trouble shoot issues.
