It can certainly do no harm to try anyway with the softer spring, and an EBC is definitely better than a simple bleed valve device.
What ecu is in the car ? and can it not control the boost ?
The Street version should do exactly what I'm wanting, it's just wether the wastegate spring needs to be any stiffer than 4psi to get 15psi max boost.
The ECU on the car is a Power Commander III USB and it hasn't got the ability to control boost.

i reckon you could get the 8psi spring to get you to 16 no problem with an EBC, stopping it spiking should be the only concern, but sorted with gain settings and closed loop etv.
The EBC spec says it has two boost control settings, so rightly/wrongly I presumed if the controller was switched off you;d get wastegate spring pressure, and with it switched on you'd have a further two boost settings.
