Mine doesn't happen all the time as yours does but I have had it happen before. Sounds to me like the clutch is slipping or not engaging. Not sure how the tune can affect it as I am not experienced in that. Hopefully someone can chime in.
That's great the dealer is willing to work with you on that knowing its tuned. Definitely have them revert to stock and test. I know it's a hassle but helps eliminate the tune and any blame on it.
