Hello!
I recently (7 days ago) purchased a 2017 Silverado duramax. I do not know much about these trucks, as I learned after purchasing it that it had been deleted when my friends looked at the truck. My intent with this vehicle was to pull a fifth wheel camper. It was suggested to me that I should learn what the existing tune was on the ECU before towing.
Are there any good ways to read an existing tune to make sure I'm not going to blow up the engine?
I have no desire for more power or black smoke. I just want to tow the camper reliably and with good fuel efficiency if possible.
