    Question Changing operating systems. From 12587604 to 12587603

    As the title states after some research it seems in some cases it is recommended to outright switch to an operating system that is more supported. Im curious if that is something possible to do if anybody has any experience in this regard and has any advice? i have a 12587604 OS from a 2004 gto ls1 m6 dbc. Is it possible to switch to a 12587603 OS from say a 2004 c5 ls1 m1 dbc? Are the tunes identical? Is all i would have to do is flash the full bin from the new OS to my car? any feedback or help would be greatly appreciated. Thanks! my bin is attached.
