Changing 6.7 Operating systems

[engr7581]

I am building a CSP5 tunefor a 2009 6.7 and my OS is 11720604. It is not one of the ones listed as able to be upgraded to CSP5. Can I just use one of the other ones that are available such as 11720809?

Thanks in advance!

Yes as long as you use a auto file for a auto etc

Thanks! Yes they are both auto trans files. There are just a few differences in the folders under internal flash is all.

Be sure your new os has the exhaust treatment and dtc tables
