Flashing the ECM never took more than a couple minutes for any of mine.The first time that you perform the tune installation, it may take you 1/2 to 1 hour, just going slow to make sure that you do it correctly. From the second time forward (if needed for additional mods, tire size changes, etc.) it should not take you any more than 15 minutes to complete. You truck won't be 'down'.
