been thinking about the exhaust flow and WG spring thing.

the spring is pushing the valve closed. that is a constant. the boost pressure from the IC is trying to open the valve, BUT....what about the exhuast pressure on the bottom of the valve?
thats pushing up on the valve trying to open that too, no?
so if the exhaust flows more freely out of the muffler then there is less exhaust pressure under the valve pushing it open thus requiring MORE boost pressure from the IC to open the WG.
i guess i will find out for sure. i have a .8 and a.6 spring on the way.
