I don’t know if this is correct but I found it in my folder of stuff I found researching online. The e9x m3 has a dct cooler working in conjunction with the heat exchanger so it seems we would add one in the same location ( before or after the heat exchanger). A diagram of that setup would be helpful I think.

Also not convinced dct temps are your issue so looking forward to seeing some logs of the boost issue and dct temp.
