A common misconception people have with this kind of stuff is that there is a manual, or a getting started file, or some sort of wizard to help get you started. I am not bashing anyone, but when you buy a homegrown DIY device it's straight up DIY on almost everything. Luckily with the Internet like minded individuals can get together (like here) and help each other out, but don't expect much more. To be 100% honest you'd probably be best having someone tune the truck for you on a dyno. If you want to learn, then you're gonna need time, patience, a wideband, lots of data logging, and many hours of Internet time. In the end add all that up and figure out what the better deal is.
