X2 Performance Chips and install?

Yes i know that most chips and their hp claims are crap, but I purchased the X2 chip and it states to connect into the MAF or into the IAT if it's separate. Is the IAT separate on my 03' 330?

Yep, seems to be nothing more than a series potentiometer (adjustable resistor). Cheats your DME into thinking more or less air is going through the MAF.
I'd imagine it tells the DME there's more air, so that it injects more fuel.
If you REALLY want to do the resistor mod, save yourself the $70 and make your own slide potentiometer:

Please install this and report back with results. More than just being poorer.

Give me a minute... let me show you what you just bought...

EDIT: I can't find that thread where the guy inquired about the GF Performance Chip. I showed him a thread on AcuraZine where someone bought a "German Engineering" box that would add mega horsepower, but was just wires that ran into a box.
