Why Choose This for Your Sierra Denali?
No more stalling during activities like towing or hauling heavy loads. Unlike failing factory modules triggering codes, this ECM restores efficiency and performance. Pair it with a diagnostic tool to monitor your vehicle’s health and catch potential issues before they become major problems.
Important Installation Notes
After installation, if the vehicle does not start, a theft relearn will need to be done using the GM programming system Tis2web/Techline Connect. This is the responsibility of the end user. Additionally, other relearns or setup procedures may be required, such as injector setup or crankshaft variation relearn.
