If you are only using the pre-loads for now, it is really simple.
Turn your truck off, plug in the SCT under the dash into the OBDII port, adn basically follow the onscreen directions. It'll let you choose which program, then tell you to turn on key, it'll load and save you factory program, and then download the tune.
You don't have to play with the different parameters yet, just get used to the tunes.
And as I always do, I would look into the custom tunes, the canned are OK, but to get what YOU want out of your truck, go custom!!
And congrats on the SCT!!
