You don't "need" one for the truck to run.

But the truck will run a LOT better with one on.

No problems updating the crom or programs here. As long as you:

1. Turn off all accessories
2. Don't pull the interface plug from your vehicle's dataport until the programmer says to,
3. Follow the step process to plug in, turn on, navigate the menu, select your options and let the tool program the car with no interruption.

Then everything will be fine.
