dump valve adjustment ?
 

just fitted a turbosmart dumpvalve to my sti 8
now i thought that to wind the adjustment screw out therefore makin the spring softer would make the valve loder and release earlier,and to wind adjuster in and make spring tighter would make the valve release higher in the rev range
am i right ?
it just seems to flutter above 3 grand and if you give it lots of revs it whooshes a little harder abd up to 3 grand it does nothing

any ideas as i thought this would be a louder valve than it is as this is what i have heard

thanks
