Definitely interested in a raw manifold.
My one concern is, and Im not sure if its a valid concern lol, but right now the way my setup is with the stock ported exhaust manifold and map o2 dump, my boost holds perfectly It spikes to 39 and falls off to like 37.8 by redline I believe the exact numbers were.
Owing to the fact that this tubular manifold moves more air, would I have to worry that trying to cram more air into my Blacks (ported) hotside and then o2 housing would begin to create boost creep?
I guess Im sort of getting at a bottlenecking type effect, where the greater volume of air trying to move thru the larger tubular manifold (versus the ported stocker), will the o2 housing or hot side present a restriction for the extra air moved by the manifold? Or is it the exact opposite?

You have it right. Look into an open O2 dump.
