I shall do that. Normally something like that shouldn't be an issue but I full flashed back in the GM OS and the truck started throwing codes and having a hay day. It almost seems like H&S has updated some controllers behind the scenes so to speak and when you flash it back to stock with EFILive your only getting the one module (Similar to the whole dodge mess).

Can anyone confirm that 12644096 is a GM OS? Has anyone flashed a truck after it has had H&S in it?

Thanks for your help.
