Got trinity replaced..

[DTatom]

Got my trinity replaced with a new one.. The old trinity would not turn on and I was stuck with the extreme tune.. So before I try to do anything with the new trinity.. What do I do? I'm still stuck on the extreme tune.. Can the new trinity I have re flash back to the stock tune? Or what?

If its a Cummins, just plug it in, load any tune, then it will let you restore the backup when you want to.

Thanks
