Didn't expect to get this much input, I really appreciate it guys! Thanks!

MAF = Mass Air Flow. Essentially it's the sensor that tells your ECU how much air is going into the engine so that it can add the proper amount of fuel. The thing is, the MAF doesn't measure all of the air going into the engine. It only samples the air and then the ECU figures out from that sampling how much is actually going in.
Say you had to count how many people go through Grand Central Station in a day. You can't count everyone, so you set up a counter at one door and multiply that number by the number of doors. Ok, that's good. But what happens if they open up more doors and don't tell you?
As for ECU tuning, yes. Very high risk because it controls EVERYTHING the engine does. If it messes up, the engine messes up. So if the ECU does not have a stock tune, any and all engine problems can be attributed to it and all engine and some transmission warranty claims will be denied.
