You can disconnect it at any time except while tuning/programming. The tune will stay on your truck and you will not be able to use the tuner on any other truck.

Wait, so I dont need to have it connected? The screen is just for show?

The screen is just for the monitoring aspect. The tune is loaded into the PCM

So I should leave it at what the shift point was? Little rough is ok?

Play around with the firmness and see if going down a couple will change it for the better. You gotta wait like 2 days each time you change something to give your ECU time to adapt but I'd say bump it down 2 or so and see how it shifts for a few days. If nothing changes then put it back to where it was.

If I'm remember correctly the 0 is just the firmness the tune is set to. It isn't stock firmness. If you have a custom tune It's just the recommended firmness for your truck set by who wrote your tune if that makes sense. I could be wrong though, I haven't read up on that stuff in a while.

At 0 it shifts firm! What is everyone running theirs at?

It will be different for everybody. From what I remember reading there were over 300 different transmission programs from the factory for the 04-08 body style.
