I just downloaded one from the net. I having a hard time understanding what everything means or how they work together. I'm not great with computers and I wish I had someone to explain just a few things

Learning this stuff is like learning a foreign language. What you may describe as "fuel tables," well the pioneers dubbed it as "volumetric efficiency" or VE tables. EPROMs can be loosely referred to as chips etc. Once you bridge the gap of that language barrier, it gets easier. TBH...I know nothing about MAF tuning. You are right that it has something to do with LV8. When I started dabbling into this stuff back in the late '90s, I didn't even own a fuel injected vehicle. My knowledge came from reading, reading, reading and more reading.

Well enough about that...with that downloaded xdf, you can open it with TunerPro. You can select an item in the parameter tree and press F2. Depending on who built the xdf, some include detailed explanations of what the parameter does. Not all of them will contain "notes" which usually means it's important but nothing needs to be changed here. Here's a good read that I searched...well I didn't read it entirely as I'm a speed density guy and MAF material is best read before bed time...
