I had the TSB done as well and still have a reduced booming. I've taken the overhead console down and saw that they didn't fix the front bow behind the sunroof and I can see that it is seperated from the roof. For the bow over the middle seat they took and smeared some glue on the edges and it won't do anything if that one is loose. They did get rid of the large boom but for whatever reason didn't fix the whole thing. Perhaps you got the same halfa$$ fix as I did.
