Is it required to go MAFless when using a 2 or 3 bar MAP with the older LS1 computers and using custom operating system #5?

Only if you're exceeding the PCM's airflow limit (512 g/s).

Is their a list of features for COS5? Or does the nitrous switch, lean cruise, 2/3 bar, Alpha-N and valet mode pretty much cover the features? My guess is all previous versions of the COS's are combined and only the COS5 is needed. Thanks.

That is the list. COS5 combines the features of all previous COS's.
