For 2010 GSR's there are only 1 tune (ROM) from the dealership. That ROM ID (55570005) inherits the definitions from 55570006. I tried my best to explain it. Maybe someone that understands it a little better can explain it more.I'm on 55570005 right now. Is there any motive towards starting on a 55570006 for my setup?
