No it doesnt show aftermarket stacks, but it talks about them. I had 2 dyno sessions at that same shop comparing various builds, from what I seen in graphs and discussed the T3 arent a large upgrade over stock, they do sound much different tho.
I did gather enough info to know that the 20v ST is a waste of time compared to the BT...lol
I am interested in seeing the differences between stock airbox and open stacks, Ive heard a few claims that there is more bottom end with the stock airbox, but who knows. I wont be doing my swap for a couple months at the very least, but I do intend to do a back to back dyno comparison between stacks and the airbox/cone filter setup many people run.
The 16v is pretty fun to play with, it can be built up to or past ST power levels pretty easily as well if you like hunting down parts
