Motor Ops uses the latest calibration information available when processing your custom ECM tuning. It is advised that all 2020+ truck owners consult their GM Dealer to ensure the TCM has the latest calibration update available. If after programming there is a Reduced Power message and/or U0101 DTC, it is likely that the ECM was updated but the TCM was not. Please reprogram the TCM.
