The length of the system might be effecting it.You may need to change the size of the first restriction.In cabin systems work well and are better than ungated engine bay type sytems as when setup properly they can virtually eliminate wastegate creep.I use an adjustable first restriction(small ball valve) and then an adjustable needle valve in the cabin and vented it back to the engine bay.I played with inline volumes and different lengths of hose until i got a slight boost spike(1psi).This method usually sees boost at lower rpm and comes on stronger as the wastegate isnt opening early.I would recomend changing to a 15 psi actuator if you intend on running 15psi or more all the time.Ive seen many turbos with 7psi actuators running bleed systems set to 15psi max with the wastegate stating to open at 5psi on the dyno.One system i played with last week had a gated bleed valve with a 7psi actuator and the exhaust backpressure was openning the wastegate fully at 10 psi.The guy didnt believe me and thought the gated bleed valve was faulty so i disconnected the actuator to prove a point.
