Hey folks,
I'm just about done installing my new MM3 from DRD. I have a quick question I'm hoping someone much more knowledgeable them me can answer.
After I have the MM3 installed and I power it up for the first time to get the stock file, can I still run the truck while I am waiting to get tunes?
Will simply powering up the unit change the stock tune it will the ECM stay stock until I manually send a tune to it?
Thanks in advance!
