The purchase of the Flashpaq 2847-DS includes the cost of the ECM Unlock and Next Day Air return shipping of your ECM. Consumers should expect a 24-48hr turn around time, we do our absolute best to limit your trucks down time to as little as three days. Our ECM modifications are safe, reliable and compatible with GM dealer tools and flashes. So, your local dealer can still interact with your truck after you’ve returned your Flashpaq tuning to factory settings.
