Hi there, thanks for that, im not sure whether to go for an uprated one or not, as its to try and fix the problem of overboosting, so im not sure if putting in an uprated one will add another problem into the system????
its a bit of a funny one, through reading various old posts on here, with similar problems, causes have been, faulty actuator, faulty map sensor or faulty solenoid.
solenoid is done, could it be that the actuator is sticky? diaphram inside it worn/leaking?
