Sku: MO-116003010301

Designed for the track and superior driving skills only for your 2020-21 Chevy Silverado or GMC Sierra. HP Tuners hardware and credits included.

Supply chain issues have made ECMs scarce. Consider our ECM Exchange product for $1089.75 CAD or $850 USD less if you can tolerate parking your vehicle for a few days while you remove and ship your ECM to HP Tuners.  We’ll provide clear instructions how to do this.  If “no down time” for your truck is more important than getting it tuned quickly, call us for the latest on ECM delivery estimates.

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.
