hi all i have a standard wrx bug eye 2002 , ive fitted a dump valve just for the noise " big kid at heart " my question is can you tell me at what rpm you get the woosh so to speak ,as mine seems to need a lot of revs before it vents to atmosphere , could this be a sign of turbo not creating enough boost pressure ?

You need to fill your car with 95 RON to get a better woosh sound after fitting one. Change up as high as you can.
After a while you'll get an awesome woosh as the pistons melt
