Basically what happens is when I stop at a light or something, the rpms will rev up and down like 300rpms consistently. Any advice?

have you done a boost leak test? i know i know everyone tells you that and im sure you have but its a start, also have you checked the biss o-ring if its the origanal it might fall apart when you touch it like mine did lol.(if you figure out what it is let me know mines surges sometimes too)
