n55 jb4 install help

hey guys how you doing

so i just got my jb4 in the mail im pretty excited but im alittle nervous installing it myself. I had a 325 before and put a tune in it and it seemed more straight forward. Anyone around here install the jb4 on the n55 engine at a certain shop or did it on your own that could teach me how to do it/ help me install it?

Thanks guys let me know

ps im going for my first service on saturday march 26 at herb chambers so i plan on installing it after that.
