the car is how i bought it, the pressure could be opening the wastegate penny but if it is its very slight, ill double check this tomorrow, as far as im aware the wastegate is wound shut, but then its on a spring so pressure will open it id imagine
sounds like a boost leak, no noise from the screamer as its not opening the wastegate due to it not making the boost it's trying to hold.
problem is what cooler, i dont want to spend hundreads on one but id like one that is as good as std or a little better but also fills the bumper gap lol
