Yes I thinks its the amal valve it is on the slam panel and one pipe goes to the turbo and the other goes to the inlet manifold i think.

So it doesnt matter if this is plugged in as long as the boost is right? or if it has it connet the boost needs turning down on the actuator so when its connected and it doubles the boost its doesnt blow the engine.

Also where would you recomend a set up around the wiltshire area?

Thanks
