Can anybody tell me what this Map has that causes it to be "Advanced"? My PC V came preloaded and I need to know if this is something I need. My set-up is: FM SE A/C, PCV, Rush 2.0's. Thanks!

 

It means there are two tables per map for each function, one for each cylinder. There are two AFR and two ignition-advance tables available and viewable. If it was a basic map you would see only one table per function and both cylinders would follow those values. Advanced is obviously better, assuming a good tune, as front and rear cylinders won't tune exactly the same.
