The fuel is not low sulfer and need to flash to a high sulfer one I can change my exhaust
As I have one from a 2008. My unit is isb 6.7 2350 101 comp 2014

Wasn't really sure what you were asking for originally.
Did you need a factory high sulphur tune (if such a thing exists) or looking to get someone to tune it for you? Either way sounds like you are all good now.

Found out about it in Africa. Equipment comes from factory without exhaust emissions
And they have to program for that . Went to dealer and they reflashed comp for 136 us
