Should it be clattering at this low boost?

You also gave me am idea. It does happen right around the shift recovery. I can add some timing retard on the 1-2 and 2-3 shift. It does jump up in boost right when i shift. Glad you pointed that out. I'm not sure i need to do a compression test yet. I hear no noises and it runs perfect still. I have a very keen ear too. thanks for the suggestions and making me realize that about the shift.
