I was going to say, 99% of the time you hear a boom under the hood like that on acceleration or other high boost circumstances, it's almost always a boot blowing off. There are 3 different boots. One off the compressor outlet of the charger, and one each on the inlet and outlet of the I/C. Also it's possible to blow the cold pipe off the intake elbow. Any of those four areas will sound the same.
I don't know about diesel shops in the Chicago land area even though I'm sure there are a few. I know of several other good shops in Illinois that I would trust my truck to.
River City diesel in Peoria.
Sasquatch diesel performance in Geneseo.
Randall's performance in Gladstone.
Hope this helps. They all have websites with contact information if you want to google them too.
