Any speed calibration reprogramming would be done in the BCM and/or ABS module, this would be accessed through the OBD port. Anything newer than an '18 model year would also need a security gateway bypass.

Welcome fellow Albertan.

To get the full AlphOBD setup which includes the app, MX+ OBD reader and a Kaodteck security cable is about 300 bucks Canadian. Just bought mine a few months ago. It can do far more than just tires/speedo. Can also reset TPMS limits, turn off seatbelt dinger, leave fogs on while on high beam, etc that the dealer will NOT do, even though they can. If all you need is the speedo corrected, the dealer can do that and it will likely be less than 300 bucks.
