I figured this much.

I had installed port deviders & it did not flow well @ all on a flow bench machine.

Turbo6 (Harry) installed port deviders on his turbo ride for better fuel distribution (he's running carbs)it help his engine from running lean on a couple cylinders ,but had to crank up the boost pressure to make the same HP as before w/out the deviders he installed.

This boost increase was needed because when you install deviders on the intake ports,your intake port window will be too small to flow well.
