Hey all. I just got a duramax that i traded my cummins for and it has efi live..
i filled out my signature and i was wondering what i have to do to be able to put different tunes on the truck.
It runs 13's in the 1/4 i was told but i didnt get anything but the truck and the keys, nothing for the efi live and im new to the duramax's
what do i need to put different tunes on my truck?
any help would be appreciated!
thanks
Kellen
