Would porting out the B6T manifold also make any difference?

Give me some feedback guys. 8)

YES! i think its a MUST on the B6T mani for sure, even on the BPT. its one thing Many dont do. it helps flow dramatically. Mazda reduced the ports on the turbo motors alot like by 1". measuring on my B6T turbo mani i ported it by 1/2" on each side of the port to match it to the DE head gasket.
