I just need a good tune for my daily driver. I don't want to do a re-learn or be without my truck for a week while the pcm is away getting tuned.

You can perform the security relearn at your own home by yourself. As far as the crank relearn, you need either a Tech 2 or tuning software to perform the relearn. You'll have to pay extra at the dealer to have the relearn done. A scan cable tune or AutoCal from Blackbear can do the relearn for you saving you the dealer trip/sending your PCM out. The truck will run without the crank relearn, it'll just run like crap and might throw misfire codes.
Here is the security relearn procedure:
Insert key, attempt to start the vehicle and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.
When the Security light goes OFF, turn the ignition to the OFF position.
Leave ignition OFF for 20 Seconds.
Attempt to start the vehicle again and leave the key in the ON position.

Once this entire procedure has been completed (three times) your vehicle will start on the fourth attempt.
Note: Some vehicles perform the relearn in a different sequence. You may notice your security light, battery light and abs light will alternate. Once the security light is left out of the sequence that is considered one step. Repeat the procedure two more times and on the fourth time your vehicle will start.
