Before you excitedly start the engine, make sure you install the Prodigy tune with the included Diablosport InTune.

It's pretty painless, but time consuming (possibly an hour or more). This is something that you could do the night before the install so that you really are ready to turn the key after putting the oil in.

First you connect the InTune to an internet-connected computer via the included USB cable. Every time the InTune powers up, it takes several minutes to go through its boot process. The first time you connect to a given computer, it will also take a while for the computer to recognize it, etc. Eventually, an updater application may automatically launch (depending on your exact OS and settings), or you might have to manually launch it (follow Diablosport's instructions).

The updater app will automatically check for updates, download, and install them. You'll have to leave the InTune connected and wait several minutes for it to process the update and reboot.

Once the updater app says it's up-to-date, you can go connect to the OBD port in the Jeep. Several minutes to power up. Then you go through the menu options to install the Prodigy tune. Follow the on-screen instructions, and be ready to do a lot of waiting.

It might tell you that your vehicle requires an update before you can install the tune. If this happens, you just unplug the InTune and take it back to the computer. plug in, wait for it to boot, wait for the updater app to launch (or launch manually if necessary). It will download and install something, probably require you to wait while it reboots, then you can finally go back out to the jeep again, where it will install the update (maybe it waits till you try to install the tune again?), then finally the tune.
