anpj vs anpk

my prom is an ANPK 6427 and im looking for a bin to start tuning but the closest I could find is ANPJ 6423.

Is this close enough? Whats the difference?

The only difference I can tell is that one if for the Camaro and the other for the Firebird. Same engine, same emissions, same tranny, same rear ratio. Would need to do a BIN comparison to see what is actually different between them.

OTOH, should be able to read out the ANPK calibration from your PROM and start with that.
