GDP Tuning

The new GDP Commander/My Diag offers a convenient option to perform the ECM upgrade on your 2017-2023 Chevy Silverado/GMC Sierra 6.6L Duramax or 2020-2022 Ford 6.7L Powerstroke in your own garage/shop. The best part? There’s no need to remove the ECM from the truck. This means there’s no risk of breaking tabs during the removal or reinstallation process. This kit also doesn’t require any reprogramming or relearns.
