are you sure youre not talking about your BOV?
no, its my wastegate. bov's dont sound like massvie exhaust leaks. besides i can fell exhaust leaking from my wastegate when the car is idling

well from what he says, its blowing exhaust out at idle which means there no tension holding the valve down. unless by chance theres some foriegn object stuck in there and holding its most likely the spring
the car makes like 7 psi at 5700 rpms lol. its gota be wastegate spring ill update tommrow when i pull the wastegate apart thanks for the info guys

ok guys i removed the lower end of the waste gate spring came flyin out and almost took off my head hahaha. anyways theres nothing wrong with the wastegate spring is fine, it was slightly jammed but once i started playing with it it moved and now is fine has full range of motion. now my only problem is how do i go about getting the spring compressed enough to put the lower end of the wastegate back on any tips or trick cause i think this is gonna suck
