Re:Boost dump89 200q

I thinks it's safe to say that your car is dumping boost
due to knock sensing, and it its doing it with the
stiffer spring, which should work OK.  Adding more spring
pressure with the knob, and disabling the boost dump
feature will make matters worse.  There is an underlying 
problem that must be addressed.  I would take out the spring 
as well, and check it's performance at stock levels, then
you can start adding back in performance as you fix things.
