So I had the dealership reflashed my ecm back to stock form. Sent the new stock tune to danville and he then built my tunes from that file. Now, finally, my trans quickly adapts shifts on my big tune! It used to take 30 min of stop and go driving to get it to somewhat adapt to my 600hp tune. Now it's twice as good after 3 take offs..crazy. my truck used to have a race evolution from edge on it so I'm thinking it left junk in my ecm..not sure. But my shifts on my 600hp tune are the best they have ever been. I also use to feel some light shuddering which is now gone. Figured I'd share this information incase others might have some of the same symptoms. I never thought my ecm tuning would play such a role in shifting!
