Definitely need to understand how these engines operate. After that, there is a pretty steep learning curve with the tuning.
That being said, it's pretty cool that Bill allows folks to tweak his tunes with the software as well. That way you can compare stock vs. tuned programs and see how the changes affect the way the truck runs and the power output. From there you can make slow and gradual changes to get used to the programming.
Be prepared to spend countless hours with it. And remember, no question is too dumb. I've asked quite a few stupid questions before. It's better safe than sorry.
