Took my 2020 Silverado to Gary Gruner to have a switch replaced and computer recalibrated after another dealership put oversized tires on the truck and failed to recalibrate the computer. The service manager, Tony Denny said the software that to be downloaded from GM to recalibrate the computer. After about 5 hours, Tony told me it might be awhile and gave me a loaner car and asked me to come back the next day. The download took 24 hours.
