Try removing the mushroom from the intake side of the filter hsg. I'd bet the perforated metal screen is restricting the flow some. You could also drop the filter canister completely and clamp on a K&N to check restriction from the canister itself. You would need to hook up your Magnahelic to the intake tube somewhere to check that out.
I think I have a 0-10" magnahelic at work in my junk box, I'll have to check.
I was already getting ready to sandblast the screen section on my intake mushroom, it has many layers of paint closing up the holes. Maybe drill them out a little, as long as I don't allow dirt daubers to get in.....
