Im sorry if this has been answered before, I looked and looked for it.

I have a unknown tune in a 12200411 PCM with a O/S12208322 BIN file loaded on it for a 4.8 motor. The motor that it came with is a 5.3 (verified with bore scope).

My question id this; Can I ONLY use BIN files written for the O/S12208322 system or can I us another BIN files made on a PCM that has a different Operating System? Thank you for your help! Motor is a 5.3 with 76mm turbo, 60lb injectors and a LS1 cam (unverified) Car will start but is pig rich rich and wont stay idling floods out and dies. Needing to load a base tune for a 5.3. Thanks again.
