Hey guys,
I know there are some threads on this from a while back but they are kind of dilluted with various questions, so.....
I've got a guy with a 6.7 Cummins, has a Smarty now but wants EFILive.... from what I read you can flash safely if you use a "pure"
stock file from a truck or one found online to create the tune, then flash it in?
I know you can't use the Smarty "stock" file for sure...
Thanks!
