I'm new to duramax motor's iv always had the 6.0 2004 and I love my duramax and will never go back. So my question is i know I can use a ecm and update the programming on a 2001 2002 2003 to a 2004 ECM what I am wondering is it possible to use the ECM out of a 6.0. To a gas burner and update the programming or Flash the programming to an 04 Duramax.
