not sure about the comp wheel... some background...
back in 2015 in the winter I tossed on the HTT turbo and set tuning back to stock to get a before and after feel of it. right off the bat it felt like a 25~30 hp/tq bump with no changes other then the turbo & afe exhaust manifold. Was running the AFE torque tube all the way up till about 2 months back where someone motivated me to put back on the OEM intake tube. That tube brought a very noticeable bump in bottom end torque. It has the turning vanes in it, 3 IIRC. It is a separate piece that sits in the lower hose. I was trying to see what the 6.7 setup looked like. The inside of the 3rd gen one has a dimpled cross setup the length of the silencer. I know the dimples are there to keep flow attached thru that section as it feeds the turning vanes at the bottom. Those vanes are helping to relieve the high pressure that occurs on the outside of the radius of the bend. Makes total sense to me why it is in there along with that center section mentioned earlier.
Here is a pic that I came across a while back while working on another truck I have (dakota 4.7) which shows the high pressure zone within the intake tube.
When I did the v4.1 of the stock air box mod, it was a very noticeable bump. Then adding stock intake tube back in it was another bump. I plan to dial it back further in an effort to extract more mpg's out of it (provided I keep my foot out of it with the air box mod being enabled... that is an awesome mod.) while bringing power back down to what I need on a daily basis. The goal is to trim duration further and tweek timing to keep it in the sweet spot while keeping the "tow" zone full fat & happy.
I am always keeping an eye out for area's to extract extra from.
