New to the forum here. Have an autocal for a 6.7 cummins 2011. Bought a different liscence for the autocal since I got it from my grandparents. I did not download the stock tune to the autocal. How do I get the stock tune back and can I just use the stock tune from my grandparents truck. It's a 2010 dodge same trans and engine. If so how would I go about doing rhis
