The one in the picture is not my TMIC but the used TMIC i recently bought has these same holes and the same location. The picture of the TMIC shown above is from a user on this board. I bought my TMIC also from a user on this board but not the same two user. So far i have seen four different pictures with TMIC with small holes on the sides. I have yet to install mine because I am sure that this needs to be addressed prior to install to assure that I will hold boost. The holes on my TMIC are not threaded so nothing was screwed into the holes at any point. The user I bought my TMIC from never had it installed, so this is why I am asking everyone, I even asked my tuner and he has no clue, as he has never seen this before.
