How many hours does it take to get a cummins update Auth #?
So I updated my EFI Live FlashScan V2 from GM only to the Cummins tuning options... I get a Invoice confirmation Email right away. Yet still no Authorization # from EFI Live.
Does there system not send out the Code # automatically like HPTuners... What gives?
