I had driven it for an hour before I flashed it, so I doubt it’s the battery thing. I did have that problem on my 14 with the Raceme but it was cold and didn’t know one of the batteries was shorted out inside. Ray said it’s something to do with the turbo mapping on these new trucks. The only reason I still wonder if I didn’t do something right is the inconsistency of it. It sounds exactly like the whistle tunes that we loaded on my dads duramax when we delete it. That was one reason I wanted to get the videos posted. To see what y’all thought and so Ray can see the difference. It seems like everything else works great though. It’s just that turbo engagement at low rpm. It doesn’t quit until it gets a few hundred rpm above idle. Maybe it’s as simple as flashing it back stock and then flashing the delete tune again. The ecm side of this stuff is out of my abilities.
