OEM ECM for Duramax trucks. All items are removed from running trucks and bench-tested before being listed. After your order, we will contact you to obtain specific information about your truck, such as your VIN and configuration, before bench-flashing your module with the most current file available from GM. After flashing, the module will be tested one more time before shipping. A VATS re-learn may be required upon installation, there are multiple ways to perform this process and a scanner is not always required. WE DO NOT OFFER ANY AFTERMARKET PROGRAMMING
