    Default Best OS, pcm year for boost?

    Hello,

    we are finishing up turbo build here and i am wondering what the best year or operating system is to use. I have access to pretty much any year gen 3 pcm. cable and dbw throttle bodies etc.

    Thanks in advance

    For LS1B, I like 02020005/COS5 which is based on OS 12212156 (2002 Camaro/Firebird for DBC, 2002 Corvette for DBW).
