Right i,ve tested boost level with electron vale connected and disconnected and its exactly the same.

How do i now find out if its the valve failed or ecu not sending a signal to it?

I had the problem of ecu not sending a signal to amal valve on 4x4 saph i had before this car. I just put in a manual switch to amal valve to overcome this to run higher boost when required.
Can this be done with electron valve?
If it is ecu problem and this can,t be done whats the solution, bleed valve?

Thanx Chris
