Trans tuning worth it for DD trucks?

The trans tune makes the transmission shift quicker than the factory tune and is well worth it to me. The truck feels completely different with it. As others have said you’ll be glad you have it once you experience the difference.

That said the only thing I don’t like at least with the GDE trans tune is the delayed shifting when below 50* But I use manual mode and shift it myself.
