I have an EFIlive licensed E38 with Serv No. 12597121 and 12618277 OS (2007 6.0 truck) that I need to make work in a 2007 5.3 Suburban. The Suburban has the same Serv No. but the OS is 12614088. According to the compatibility chart it says the 6.0 PCM is a 2008 OS and the Suburban is a 2007.

Is there any way to make this work?
