N54 30FE custom tune issues

Hi all! I'm new to tuning and writing my own tunes and such. I just always let someone else do it for me but I'm wanting to learn how it's done or at least get a good understanding. While writing my own tune basically based off a BEF from MHD I end up running into a 30FE code for overboost. Can anyone guide me in a general direction as to what to look for or what they've had to do whenever encountering this similar issue. I can upload a graph if I need to. Im at about 30 percent waste gate duty and 8 pounds of boost about 3k rpm whenever I experience the over boost. I'm within 1 pound of target boost.
