I have not. haven't needed it. things to consider:
1. Will it impact warranty
2 there is a reason the Cummins engineers didn't do it
3. There are reports of substantial def emission system problems on some diesels with tuners
4. search YouTube or web for various reports of blown diesel engines due to tuners.
Let us know what you find.
Good luck
