Leaking blow off valve?

[Richard]

Ok so I've read a bit recently about everyone has trouble holding boost and it always seems to be the factory blow off valve cant hold the boost pressure it is being asked to. My question is if an aftermarket valve is fitted that vents to the atmosphere is leaking will you hear it? Obviosly it can be heard when the throttle is snapped shut but under steady hard exeleration the boost initially reaches 15psi then slowly leakes back and sits at 10psi. Is the problem; the blow off valve leaking ( http://www.gofastbits.com.au/index....cts&sub_option=bovs&sub_sub_option=stealth_fx ), The turbo is not able to supply a constant 15psi ( TDO4 L ), the boost control valve ( http://cgi.ebay.com.au/Turbotech-ma...3QQihZ010QQcategoryZ43808QQrdZ1QQcmdZViewItem ) is faulty/crap, or ???
